Extract all native DSDT/SSDT from Linux.

Find the SSDT with _OFF for your nvidia (it will have a bunch of PEGP/PEG0 stuff).
Call _OFF from the associated _INI.

This is all file i dump from linux
View attachment dsdtssdt dump linux.rar
but i don't find _OFF in SSDT2 (i think SSDT2 for nvidia)
i follow a guide (add to SSDT2)
External (\_SB_.PCI0.P0P2.PEGP._OFF, MethodObj) // 0 Arguments
...
Method (_INI, 0, NotSerialized)
{
If (CondRefOf (\_SB.PCI0.P0P2.PEGP._OFF))
{
\_SB.PCI0.P0P2.PEGP._OFF ()
}

Store (Zero, \_SB.PCI0.P0P2.PEGP._ADR)
}
...

Compile --> SSDT.aml and push to /Extra then restart but not work. Do you think i am wrong ?
Thank.

It can also be _PS3. It doesn't make any sense to attempt to call a method that doesn't exist.

Sorry, i don't remember but recommend u use 2 ssdt, example ssdt.aml for nvidia ( same like ssdt2 in my 1st post), and ssdt-1 for disable it. Don't forget rename IGPU-> GFX0. Use _OFF for ssdt-1. Don't give up, i lost 2 months and 1 HDD for this . (sr for my english ).
