Can't activate hardware acceleration on HD Graphics 4000 - Ivy Bridge

Hello everyone, I'm trying for quite some time but can't seem to make my iGPU to work properly. So far, I've tried Catalina, Big Sur and even Sonoma (applying OCLP patches) but nothing seems to make the acceleration activate. Tried different framebuffers, no_compat_check flag, multiple NVRAM resets, double checked my BIOS settings and config.plist, but I cant see what am I missing. Any ideas?

Specs:
CPU: Intel Core i7-3770
GPU: Intel HD 4000
RAM: 16GB DDR3 @ 1600Mhz
Chipset: B75 Revenger (Chinese rebrand)
Storage: 240GB Netac NVME SSD
