[Request] Gigabyte G5 KF

Hey guys, I recently bought a Gigabyte G5 KF and the undervolt settings is locked and BIOS is barebones. Is it possible to unlock undervolting for the 15 12500H?

can you please also help me for this? The same laptop model.

Original bios link is here. It works around 100 degree and I would like to undervolt it
