Hello, I have an ideapad gaming 3 laptop and I would like to unlock the bios to unlock the undervolt of the cpu and the gpu, also to increase the tdp of the gpu from 50w to 60w

Yes, the cpu was unlocked but it seems to be slightly unstable, I also want to configure the gpu, I feel that its full potential is wasted because it only reaches 68c with peaks of 70c stressing it in furmark
