How to remove Google Mobile Services from Package? (OculusGo Requirement)


I’m trying to port a GearVR Game to OculusGo. It’s not a big deal, because it’s nearly the same.
But there is one restriction. Google Mobile Services have to be disabled.

Oculus says: “The package uses Google Mobile Services, which is not supported on this device.”

Google Play Support is set to false, but that doesn’t help.
All the PlugIns are disabled.

Does anybody know how to fix it?

Thanks in advance,
