[REQUEST] ASUS TUF F15 (2021) 11400h + 3060 unlocked bios

Hey there, just wondering if anyone can guide me in the right direction to mod the bios to unlock the hidden menus for undervolting. I can see that mods have been made for similar models with the same cpu on various forums so I understand that it is possible.

I am currently on bios 313 and I also have a CH431a handy to reflash incase something goes wrong. Could someone help me out?
