In Infinity War they made a big point of saying it's possible that they could separate Vision from the mind stone and still have most of Vision left, with the right technology, and also made it a point that Shuri was smart enough to do it. When she was working on it in the battle towards the end it looked like she saved the work she had before evacuating.

Endgame confirmed that she got dusted, but I think that in Phase 4 there's a good chance that they show her having completed the work to bring a form of Vision back...
