For this Asus model, it seems like _PS3 is the right method to call:

        Method (_PS3, 0, NotSerialized)
        {
            Store (0xD3, DBG8)
            If (LEqual (\OMPR, 0x03))
            {
                Store ("PS3: Driver wants to power off dGPU", Debug)
                If (LEqual (DGPS, Zero))
                {
                    Store (0xC3, DBG8)
                    \_SB.PCI0.LPCB.EC0.TSDS ()
                    \_SB.PCI0.PEGR.GFX0.DOFF ()
                    Store (One, DGPS)
                    Store (0xC4, DBG8)
                }

                Store (0x02, \OMPR)
                Store ("PS3: OMPR=2 now", Debug)
            }

            Store (0x03, _PSC)
        }

PS0 to power it on:

       Method (_PS0, 0, NotSerialized)
        {
            Store (0xD0, DBG8)
            Store (Zero, _PSC)
            If (LNotEqual (DGPS, Zero))
            {
                Store ("PS0: Need to power on dGPU", Debug)
                Store (0xC1, DBG8)
                \_SB.PCI0.PEGR.GFX0.DON ()
                Store (0xC2, DBG8)
                Store (Zero, DGPS)
                Store (Zero, \_SB.PCI0.PEGR.HDAE)
                \_SB.PCI0.LPCB.EC0.TSES ()
            }
        }
