Enabling SteamVR Input in 4.21?

Is there a way to enable SteamVR Input in 4.21 that doesn’t involve editing CVarEnableVRInput in SteamVRController.cpp and rebuilding the engine?

Typing “vr.SteamVR.EnableVRInput 1” gives an error because it’s a read only variable, and there doesn’t seem to be anything in project settings to change it.

Do it in the .ini file.

Which one? And what do I need to add? (none of the Default*.inis refer to that variable)

[edit]Adding it to ConsoleVariables.ini sets it. But that makes it global, is there a per project way to set it?
