Flipping the switch via ACPI

If you’re wanting to switch off the dGPU via ACPI it’s possible to use acpi_call in order to switch off the NVIDIA RTX 3050 Mobile.

Who you gonna call?

Simply writing \_SB_.PCI0.GPP0.PG00._OFF to ACPI via acpi_call results in the dGPU being powered off.

echo '\_SB_.PCI0.GPP0.PG00._OFF' > call
