At least with V you find out that the chip is Arasaka's multi-trillion dollar magnum opus, and requires multiple other technologies and systems that they alone control, thereby explaining why its not so simple to fix or remove (given its literally keeping his brain in tact as well).
As a side note I believe the upcoming Phantom Liberty DLC for Cyberpunk 2077 is actually going to change all this in that it will allow for a new ending where your V is perhaps not doomed at all.
I do wonder just how extensive a Definite Edition of Baldur's Gate 3 changes could really be, I wouldn't innately expect anything grand, but it's been awhile since I've compared the differences between Normal and Definitive edition of Divinity original sin 2.
