MacbookPro16,2 SMBIOS didn't help

Have you added -igfxadc=0 -no_compat_check to the boot-arg?

Also device properties for the IGPU need to be this:

I have managed to install MacOS Monterey 12.5. It looks like issue was in enabling iGPU. My Intel Graphics has device id equal to 0x9BC4 so I set AAPL,ig-platform-id value equal to C49B0300 and was able to install MacOS, but ... system reports only 35Mb for my Graphics and UHD screen performs very slow. BIOS reports DVMT Pre-Allocated = 64Mb. I have tried to implicitly set it via modGrubShell, but not sure that it applied correctly.

Also I have tried to run installer with boot-args: -v debug=0x100 keepsyms=1 -wegnoegpu -igfxmpc igfxfw=2 igfxonln=1

It didn't helped. Any ideas how to speed up graphics?

the required DeviceProperties settings are in my laptop guide:

A guide in setting up your USB installer using OpenCore. You must have either a built-in ethernet or compatible Broadcom Wifi in your laptop for this guide to work. Built-in Intel Wifi can also work if set correctly...

i have already seen your config.plist, hence my response to you about the parts that are missing in your DeviceProperties section

Do you mean framebuffer-* settings? I don't actually need framebuffer-patch and framebuffer-fbmem.
