[REQUEST] Huawei Matebook X Pro Unlock

Hi guys, for hackintosh purposes, I would be pleased to have the advanced menu of my laptop unlocked, and change my DVMT value to 96 or 128mb although I think the max might be 64mb, and the DVMT Total Gfx Mem set to max. I tried to change the values with EFI Shell but it outputs an error when I type setup_var 0xDF 0x2.(error: 0x000000000000000008)
Laptop:
HUAWEI Matebook X Pro I7 16G+512GB (Mach-W29C)

How should I Dump my bios? I have a .FD bios file, but I don't think that's it.
Thank you all!
