AoT operates under a fixed timeline/stable time loop principle. The past (and the future) cannot be changed.

We won't see this rule broken because if it could, then Chapter 121 wouldn't have played out the way it did. That was when Eren and Zeke visited Grisha's memories when he killed the Reiss family. Chapter 121 literally only exists so Eren could visit his father's memories and ensure past Grisha could be persuaded into forming the timeline as we know it.

My feeling is that Eren will succeed in his plan as far as his vision of the future has shown him (because the timeline cannot be changed), but the future has a silver lining that no one besides possibly Eren is currently aware of. I dunno, I still feel like it's possible that this isn't a fixed timeline. I wish Isayama would outright say whether it is or not so arguments like this could be settled, but that's beside the point.

It doesn't have to be a time maneuver, just a means to travel to the Paths realm in an attempt to stop/convince Eren. Eren then flips the tables on them, showing them what is to come.
