You need to know which PCI slot you want to disable (this is where you have your Nvidia card) and then create an SSDT or modify your DSDT with the following.
Code:
Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
                {
                    If (LNot (Arg2))
                    {
                        Return (Buffer (One)
                        {
                             0x03                                           
                        })
                    }

                    Return (Package (0x06)
                    {
                        "name",
                        Buffer (0x09)
                        {
                            "#display"
                        },

                        "IOName",
                        "#display",
                        "class-code",
                        Buffer (0x04)
                        {
                             0xFF, 0xFF, 0xFF, 0xFF                         
                        }
                    })
                }
Now macOS will not recognize your Nvidia card, then you must go to windows and disable your AMD card.
You must use 2 different cables connected to your monitor, and depending on what you want to boot, change the input of your monitor.

If you decide to change SMBios you must do it to iMac 19,2 since it uses an 8700k, the closest thing to your 8600k.

If you’re running 10.14.5 with an i7-9700K, it will recognize the CPU as an i7. But if you use 0x1005 it will incorrectly set it to an i9.

Hello everybody,

I follow the thread to configure my i9 9900k to get headless iGPU
my config boot with clover r4934, SMBIOS19,1 (i9 + sapphire Vega 64)
in Hackintool, I got Platform ID 0x3E910003 (It should be 0x3E980003 with platform-id right ??)

It's seems to be OK, I don't have iGPU in hardware info and MacX video detect UHD 630 but not CFL ..
and I can't boot without WEG, kernel panic at apple logo

407964


what I've missing ?

Do you have to be on the latest Mojave release in order to change SMBIOS to an iMac19,1/2 definition? I'm still on High Sierra 10.13.6 and quite happy for a while before I get time to upgrade OS. Currently running iMac 18,3 def with 8700K and RX580 with Quicksync.
