[REQUEST] HP Envy x360 Convertible AMD Laptop VRAM increase BIOS mod

[whitelighter]

Hello there I'm currently on F.21 BIOS and there is no where to increase VRAM to 1GB which is needed for NootedRed's kext on Vega 8 iGPU for opencore. I've tried Smokeless_UMAF but to no avail. Does anybody have an already modded bios or another way to increase that pesky vram from 256mb to 1GB? thank you for any help here!
