Is there a guide like this to disable a RX570 in Catalina? I’m running a triple boot. Windows 10/Catalina(5700XT) and Mojave(RX570)

to both of you, if the file posted above is not working, try this second one, I use it on my own computer with success.
The previous one was for ACPI path "_SB.PCI0.PEG0", this one is for "_SB.PCI0.PEG0.PEGP". Copy to EFI/Clover/ACPI/Patched folder then reboot.

This DSDT file works for my system with an NVIDIA RTX 2080 running in a ASUS Prime Z390-A on Catalina!

Is it possible to somehow have the BIOS manage ASPM? The graphics card still draws 50 Watts of power doing nothing!
