Agreed, I don't intend on messing with my BIOS and don't mean to encourage anyone to do so.
Edit:
I'm quite positive I've read an official PCS article about teaming up with XMG to use their BIOS when the laptops had initial problems with RTX graphics stutters (back at the launch). Can't find it...
Late reply to the OP. Having the exact same laptop I can confirm few things. In my system I noticed in several cases that the VRAM temps went up to 106*. Laptop was cooled with air and without any stand (for me it happened during Assasins Creed gameplay with a lot and lot of NPC around me)...
