How to properly configure iGPU with HD630 + Vega 56?

I've seen a lot of tutorials and tried a lot of things, but nothing has worked so far.

My setup is this: i7700k, Z270XP-SLI, Vega 56 LE.

My config.plist is here:

Kexts: WhateverGreen, USBInjectAll, Radeon56Fixetc.., FakeSMC, Lilu, IntelMausiEthernet, XHCI-200-series-injector

Most confusing points:

- Is -disablegfxfirmware necessary?

- Should I set iGPU on Auto or Enabled? Because if I put Enabled, I get this kernel panic on boot: https://imgur.com/a/9AejpCV.

- Is it correct to put 0x59128086 on fake iGFX? I saw some tutorials using it + 0x59120000 on platform-id, but since I'm using the Vega, my platform-id is 59120003.

- Should I use AppleIntelKBLGraphics.kext? If so, should I also use FakePCIID and FakePCIID_Intel_HD_Graphics, as per this tutorial?

- I also saw some people suggesting OS-X-Fake-PCI-ID for FakePCIID.kext, but it doesn't have HD630, only HD620.

I also saw Intel Framebuffer patching using WhateverGreen, HOW TO FIX VIDEO RENDERING ISSUES IN FCPX HIGH SIERRA and How to enable 'Kaby Lake' Intel 6xx Graphics (10.12.6+), but so far without any real progress.
