AMS2 with PP off - can't get it to work

Im trying to use the trick to get AMS2 to work with PP off, but it’s not working based on what the youtube video showed. It keeps opening SteamVR the same way it was before. In my library I already had AMS2 listed even though I imported the game again and put that appid text file in there as well.

How do I force it to use oculus runtime?

@park had a tutorial involving changing some numbers in steam_ap.id(?) File.

Opencomposite might also work. Kind of like a reverse Revive.
