To disable nVidia try to insert

\_SB.PCI0.PEG1.GFX0._OFF ()

into \_SB.PCI0._INI

    Scope (_SB.PCI0)
   {
       Method (_INI, 0, NotSerialized)
       {
           \_SB.PCI0.PEG1.GFX0._OFF ()
           Store (0x07D0, OSYS)
           ...

If it turns on again after sleep, insert it also into _WAK

    Method (_WAK, 1, Serialized)
   {
       \_SB.PCI0.PEG1.GFX0._OFF ()
       WAK (Arg0)
       ...
