[Request] Unlocked Gigabyte Aorus 15G YC BIOS

Hello, my aorus 15 (yc) laptop overheats quickly and I want to lower the frequencies but like all aorus laptops, the bios is locked, I have zero knowledge of bios modification and I am afraid of touching something and it will break, so I am asking for your help.
I managed to get the rom from the aorus download page, which was inside the laptop’s bios updater
I attach it, I would like you to explain to me how I modify it, or help me modify it and explain to me how I install it.
I’m still not sure if the rom inside the exe of updating the bios on the Aorus page is okay.
