No worries. It happens. I'm also about to signoff. Long day and coding stuffs.
Okay, so the Device ID is not natively supported.
Install latest FakePCIID and FakePCIID_Intel_HD_Graphics.kext to S/L/E.

Is it really necessary to install in s/l/e? Why not in clover? I observed them working ok from clover c/k/o.
What about weg? Shall I remove it?

I prefer FakePCIID installation to S/L/E. Of course it can be installed to CLOVER/Kexts/Other.
No need to remove WEG. Keep that and also install both the FakePCIID.

Well, I can simply return a package from ssdt dsm, no need to use fakepciid if there's still weg, I suppose.
Like this code in the IGFX _DSM observed on my real mac:


So, in my _DSM I can just

              Return (Package()
                {
                    "model", Buffer() { "Intel UHD 620" },
                    "AAPL,ig-platform-id", Buffer() { 0x00, 0x00, 0x16, 0x59 },
                    "device-id", Buffer() { 0x16, 0x59, 0x00, 0x00 },
                    "hda-gfx", Buffer() { "onboard-1" },
                })

For all UUIDS, except wintel's 3E5B41C6-EB1D-4260-9D15-C71FBADAE414

But ok, I did not succeed, so will follow your instructions, thank you!
Do I need to enable injection in some other way? It does nothing without it.

I still prefer FakePCIID method. No any other way to inject except DSDT and Kext.

Sure, this is dsdt.
Ok, doesn't matter, but my question was - do I need to change clover's config prior to sending you files? Because I just put both fakepciid back and observe no changes. And it shall be so since no injections are configured in clover. I can send you files as they are now but I suppose without igpu properties injection, they are the same as I sent you before?
