How to increase VRAM and Open Hardware Acceleration of AMD APU

[mroz1275]

Hi. I'm trying to make a hackintosh on my HP Probook 455G9 with AMD 5825U APU (Vega 8 Integrated). The problem is BIOS is locked for changing the VRAM even though I have 16GB RAM and NootedRed. Therefore, I can't increase the stock VRAM which is 512mb currently. I tried using Smokeless UMAF but the option for changing the VRAM or UMA Buffer Size didn't show up there. What is the way to increase VRAM in this case?

This is my EFI Link

Unfortunately, unlocking the BIOS is the only way, if you have confirmed that the VRAM is 512MiB only.

Yeah I got it. Thank you
