VRDevice Oculus cannot be disabled on this platform.

Using Unity 2018.3.12, Oculus Go platform. I'm trying to get the Go controller to act as a laser pointer and installed the helper stuff from a blog here. It works, but in the log I get a constant stream of "VRDevice Oculus cannot be disabled on this platform."  I searched all sources and this is not something in code I can see.
What's going on? I'm sure I'm not trying to disable it.
