apparently that is needed for the spoof to work according to Rehabman the other day when he mentioned in another post

Not needed with correctly coded SSDT-DiscreteSpoof.aml.
Each is two different methods for doing the same thing (injecting the various properties to spoof the devices as "not a graphics device").
 
Even with the spoof script that disables Nvidia?

Your SSDT-DiscreteSpoof.aml is not likely to work due to disabled _DSM->XDSM patch.
 
How do I enable that?

Look at your config.plist in config.plist/ACPI/DSDT/Patches. You will notice the _DSM patch has Disabled=true. Set to false instead.

I'm still having the same issue after editing the config file.

How do I boot with inlaid ig-platform-id?

Two ways:
- set in Clover options -> Graphics -> ig-platform-id (0x12345678)
OR
- set in config.plist/Graphics/ig-platform-id=0x12345678
