Hi
@jiffyslot, I'll reply further tomorrow as I'm just about to retire for the night, I have work starting at 7am in the morning...
Just a quick note though (well slightly longer than quick!).
If you are using the Intel UHD 630 in headless mode, ie just for quick sync, then it should not show in System Information as does in your screen capture. I believe this is what you are trying to achieve. Also some 'Hackingtosh' kexts don't actually load, they are just a method of injecting or changing other system things. Use the 'Extensions' settings in System Information, and once it loads (it can take a little while to troll through all the kexts in your system) then in the far right column sort it so it shows the non-signed kexts, and you will see what ones have been loaded etc.
Only when you have set it up to be used as a display driver either as a stand alone or in conjunction with your RX 580, should it show in System Information.
This is from memory, as typing on a Windows PC, but under Mojave and think HS, you set the two BIOS settings for the iGPU to 64MB & Max. Things have changed very recently, and under Mojave, you no longer have to have the ig_platform_id set ie leave it blank and definitely don't tick the 'inject Intel'. Use the latest whatevergreen.kext (I think its up to version 1.27 or later now) in your /Library/Extensions get rid of FakePCIID_Intel_HD. Do the usual Update of your kernel cache etc... sudo touch /Library/Extensions && sudo touch /System/Library/Extensions && sudo kextcache -i /
I'm guessing you have USB configuration problems and some other issues... eg NullCPUPower… is no longer needed on this Mobo, and also FakePCIID_XHCIMux… also is not needed if you are either using rehabmans SSDT method of patching USB or my preferred method of FB Patcher (far easier).
I can't see your config.plist ATM, but I'm guessing there is other issues.
I only have two kexts in my clover EFI other folder, and all my USB ports are working, plus powernap, etc maybe because of the time difference you can show a file list of your EFI folder(s) in a code window and also your /L/E folder as well.
I have been using 18,3 for a long time now, and all is well in my world. 14,2 works well as a starter for most hacks, but IMHO 18,3 is the one we should be using on this system. I'm also using the very latest Clover. I have reverted back to HFS+ a few days ago, as I don't like the longer boot times using APFS, as it pauses to Trim my SSDs and I also have an app that allows me native access to HFS+ whilst dual booting from Windows 10.
