Need help with Intel UHD 630 framebuffer/QE/CI on Comet Lake (i7-10700, ASUS B560, macOS Tahoe)

I've been fighting with this Hackintosh for days and I'm running out of ideas.

**Specs:**

* i7-10700 (Comet Lake)
* Intel UHD 630 (`0x3B9B8086`)
* ASUS PRIME B560M-A
* macOS Tahoe
* OpenCore 1.0.7
* `iMac20,1` SMBIOS

The system boots fine, but I have **no graphics acceleration**. Hackintool shows `IONDRVFramebuffer`, only **7 MB VRAM**, QE/CI is disabled, and Metal isn't working.

Latest Lilu and WhateverGreen are installed and loading correctly. USB works, display output works, but acceleration never kicks in.

Some things I've already tried:

* Different `AAPL,ig-platform-id` values (`00009B3E` and `07009B3E`)
* Different framebuffer patches
* Resetting NVRAM after changes
* Various `device-id` combinations

One weird thing is that if I remove the `device-id` spoof, I just get a black screen. Right now I'm using `9B3B0000`, which lets the system boot.

Also, `ioreg -lw0 | grep -i AppleIntelFramebuffer` returns nothing at all, which makes me think the framebuffer driver isn't attaching.

I'm using the **motherboard HDMI port** for display.

Has anyone gotten a Comet Lake UHD 630 (`0x3B9B`) working on Tahoe, especially on a B560 board? I'd really appreciate seeing a known-good `DeviceProperties` section or hearing if I'm missing something obvious.
