Did you create your own config.plist via the Dortania guide or just use the one from Zearp ? If you followed Zearp's GitHub thread there may be some things tailored to using HD4600 exclusively instead of a dedicated gfx card with iGPU running headless. I haven't looked at that in great detail yet. Will take some going over your config.plist to see what is keeping it from working. I'm off to work now, so won't be able to assist till later this evening or tomorrow.
Take care!
I have resolved the issue by double checking my BIOS settings and finding;
- Primary Display Adapter -> AUTO
- Multi-Monitor Mode -> Disabled
After changing these to;
- Primary Display Adapter -> dGPU
- Multi-Monitor Mode -> Enabled
with AAPL,ig-platform-id set to 04001204 VDA Decoder is now Fully Supported.
I used jaymonkey's Lilu guide you previous linked on the Golden Build to find this was the cause of my problems.

Thanks trs for your help!
I tried following the Dortania guide but it would hang up on boot with "PCI configuration end.... \n Couldn't alloc class" or "ifnet_attach: all kernal threads created for interface lo0... proceeding". I have no idea what any of this means?
So i followed Zearp's thread starting with a naked 9020MT using his complete EFI, This thread for bios mods, Installed Catalina, Following Zearp's USB portmap to remap the 9020MT so i can use the internal USB header, I then proceeded to build upon his config.plist to suite my needs whilst installing my hardware (dGPU, NVMe...) updating to the latest release of opencore. along with updating to the newest kexts. Then finally upgrading OSX to the Big Sur beta
I have attached my current EFI that seems to have everything working (i've not tested integrated audio as i have a USB DAC), Though the USB mapping (USBPorts.kext) is still quirky as i've only mapped one of the front USB 3 headers as in my set up i have converted the 2 Dell USB3's into USB2's and only utilise 1 USB3 port because i have a funky 5.25" SD card reader that has a usb3 port, In hindsight I should have used the USB3 to USB2 adaptor on this port maintaining 2 front USB3 ports, enabling me to map these properly.
This is a screenshot of my USB mapping, HS11 and SSP1 is the missing front USB3 port.
