[HELP] - Disable RTX3080FE

[lesnico]

Hello everyone,

I've succeeded at installing MacOS Big Sur on my computer and for the most part, it works great!

I've got one big issue however that I can't seem to resolve.
I have two GPUs on my computer, a RTX3080 fe on the first PCI-E SLOT (x16) for gaming in Windows and a rx480 4go on the second for MacOS.

I can't disable my RTX3080 fe and I need to do it because it prevents my computer to sleep normally.

When it is installed on my computer, my computer takes a super long time to sleep and wake up from sleep.

I've tried bot methods explained on the dortania guide:
 

DeviceProperties Method

PciRoot(0x0)/Pci(0x3,0x1)/Pci(0x0,0x0) name data 23646973706C6179 IOName string #display class-code data FFFFFFFF

But the gpu is still there when I reboot.
 

SSDT Method

I've found the PCI-E path on windows (Location path) and converted it as explained. It gave me this result :

 

_SB_.PCI0.GPP8.GFX1

 

And here's my Spoof-SSDT.dsl:
 

 

DefinitionBlock ("", "SSDT", 2, "DRTNIA", "spoof", 0x00000000)
{
    External (_SB_.PCI0.GPP8.GFX1, DeviceObj)

    Method (_SB_.PCI0.GPP8.GFX1._DSM, 4, NotSerialized)
    {
        If ((!Arg2 || !_OSI ("Darwin")))
        {
            Return (Buffer (One)
            {
                 0x03
            })
        }

        Return (Package (0x0A)
        {
            "name",
            Buffer (0x09)
            {
                "#display"
            },

            "IOName",
            "#display",
            "class-code",
            Buffer (0x04)
            {
                 0xFF, 0xFF, 0xFF, 0xFF
            }
        })
    }
}

 

But it also doesn't work.

Finally, I found on a german forum that if I add the following entry to my config.plist, it's now working but the boot time of my Hackintosh is very slow (2,3mn) :
 

device_type	string	VGA compatible controller

What could be the issue here?
I've spent litteraly the entire night browsing google to try to find an answer but nothing, hence why I'm turning to you.

I've attached my RunMe-Output folder

Thank you for your help!

the device is missing inside gpp8

i create one gpp8/pegp with _adr 0 and disable this disable. in this case disable pegp inside gpp8

if disable entire gpp8 cause this problem. common in some cases
