Acer predator helios 300 i7 10750h rtx 3070

Hi, i have the acer predator helios 300 i7 10750h rtx 3070 PH315-53-71CM Bios version V2,04

I would like to try get acces to undervolt cpu in bios and remove the 100w gpu limit thats on it currently.

Im going to try do it myself but i havent even looked at the guide yet and i have never done anything like this before so some help would be amazing, if you need any files just ask but you can download the bios from the asus website
