No, manga Deku cannot go 100% without Eri. He has been training to use 100% of One For All without breaking his body, but he has not yet reached that point. He can use 45% of One For All at full power, and he can use 100% for short bursts of time with the help of his new quirk, Fa Jin.
To sum it up, Midoriya cannot use 100 percent of One For All without the help of Eri since it would put his body at risk. The consequences can be so bad that it could lead to his death if he uses it without training his body until it can handle it.

3 Deku Never Will Beat: Overhaul (Without Help)
Deku's determination certainly played a part, but so did Eri's quirk. We'll never know if Deku could have won that fight solely on his own. He'll certainly never get the chance for a rematch, what with the current status of Overhaul and all. It's almost a shame.
Midoriya, in the manga is able to use 8% of One for All without experiencing any pain. However, when push comes to shove, he is able to maintain the continuous flow of 20% One for All in his body for a short period of time..
Blackwhip was the first Quirk within the One For All that Deku awakened. Due to this Quirk's ability to produce webs of energy that can be used as ropes, this Quirk is quite useful. In combat, it can also be combined with other Quirks and is thus one of the best abilities that Deku possesses.
Even his 100% punch isn't enough against the guy. Then in a last minute effort after the water boy distracts the muscle guy with his power, Deku turns his power up to a million percent.
Weaknesses: She has no control over her own Quirk and thus can harm others around her even if they are her allies. She is extremely traumatized by her experiences as Overhaul's prisoner, which can be used to manipulate her.
when creating the bullets in the first place Dr. garaki was then able to get a version of Aries Quirk from this that couldn't be turned off and all for one took this to make sure that no matter what he reaches shigaraki's Battlefield where he can then do something to save himself.
This also means Eri cannot use her Quirk on time as it is not a living thing. Two months prior to the raid on the Paranormal Liberation Front, Eri trained her Quirk on small bugs and lizards, using small ounces of energy. She was eventually able to restore the Permeation Quirk of Mirio Togata the day before.
Full Cowl at 100% dramatically increases all of Izuku's abilities, granting him strength and speed that rival that of All Might, and the ability to move through mid-air using wind pressure. At 100%, Izuku completely outmatched Overhaul in his final form.
During the Dark Hero Arc, Izuku's strength increases even further and he can now use 45% as his regular output with no backlash.
Description. Izuku uses both his 100% Delaware Smash and his 100% Detroit Smash at the same time, multiplying their destructive power into one attack. It is one of the strongest Ultimate Moves in Izuku's arsenal.
Deku's final quirk is known as 'gearshift'. It's a quirk that is activated via physical contact. It allows the user to change the velocity of anything they touch, meaning they can spontaneously slow things down, or speed things up.
Gearshift: The Quirk wielded by the second user. This Quirk allows the user to alter the speed of anything they touch, allowing them to accelerate the force of a target, either by enhancing the impact force of their own strikes or by causing the target to lose control of their own velocity.
As of now, Deku has access to seven Quirks, namely One For All, Transmission, Fa Jin, Danger Sense, Blackwhip, Smokescreen, and Float. The basic gist of all these powers is that they all come from the previous One For All users, with their abilities becoming stronger throughout the generations.
However, in her true nature, Eri holds a murderously hatred towards Shizuku for being Kouki's childhood friend (although she is Hajime's lover) as she wanted to kill her and the rest of their classmates to claim Kouki for herself. She considered Shizuku as one of her mortal enemies (along with Kaori).
The man that would be known as Nine was born with a Quirk that allowed him to control and manipulate the weather around him. His Quirk was immensely powerful and was viewed as a god-like ability. At the same time though, Nine was one of the many who felt outcasted in society and believed that it should not be this way.
All For One is, quite possibly, the strongest Quirk there is in My Hero Academia. It was formerly wielded by All For One and is currently in Shigaraki Tomura's possession.
Quirk. Rewind: Eri's Quirk allows her to rewind the state of a living being, this includes her reverting a person's age and, as shown with her father, being able to rewind a person out of existence.
After 369 chapters of My Hero Academia, Deku can finally truly call One For All his own Quirk as he unleashes its full power for battle.
A 100% Smash is already strong enough to break several bones. 1,000,000% is complete overkill by this point in My Hero Academia. Deku combines the raw power of both his 100% Delaware Smash and 100% Detroit Smash.
Don't automatically say he can still use only 45%. Literal months passed since he could use 45%, so he must be able to use more of One for All. Not counting Fa Jin, I would guess the percentage that Izuku could use is closer to like 60 or 65 percent.
