Lenovo Yoge Pro 9I (14IPR8) Bios mod help/request H2o

Hello,

I’m trying since a few weeks now to understand and mod my bios to enable Advanced settings in my bios to undervolt ect…

I’ve tried multiple things but the most I could get that I could understand is this from H2OUVE :

Here is the bios I’m trying to modify.

If anyone could help that would be appreciated :slight_smile:
Thanks and have a nice day !
