Your DGPU _OFF method is: \_SB.PCI0.PEG0.PEGP._OFF()
It is in the DSDT file.

You may need the following SSDT in clover ACPI/patched folder:

DefinitionBlock ("", "SSDT", 2, "hack", "DGPU_OFF", 0x00000000)
{
    External (_SB_.PCI0.PEG0.PEGP._OFF, MethodObj)    // 0 Arguments (from opcode)

    Device (_SB.FJHK)
    {
        Name (_HID, EisaId ("PNP0C02"))  // _HID: Hardware ID
        Name (_CID, "DGPUOFF")  // _CID: Compatible ID
        Method (_INI, 0, NotSerialized)  // _INI: Initialize
        {
            If (CondRefOf (\_SB.PCI0.PEG0.PEGP._OFF))
            {
                \_SB.PCI0.PEG0.PEGP._OFF ()
            }
        }
    }
}

Hello,

Im currently using the SSDT attached to this post.

What happens is, when i power on my laptop it works, and my nvidia card is succesfully disabled. But if i restart the card comes back on.

Only when i shutdown my laptop and power back on that the SSDT works again.

Can anyone help me to fix this please?

One question, I'm updating from High Sierra to Catalina, all is ok, audio, battery, brightness keys, all are working fine, but
how can I disable the discrete graphic if when search using grep on terminal didn't find nothing?

I tried:

grep -l Method.*_INI *.dsl
grep -l Method.*_OFF *.dsl

And nothing found.
