In Varwin, as of version 17, it is now possible to switch the VR application runtime environment from SteamVR OpenXR to OpenXR for each individual headset developer. This is done in each individual app that comes with the headset, such as Oculus, Vive Business Streaming, etc. Some apps can only work through SteamVR OpenXR, so you'll have to use SteamVR for those anyway:

  • Pico Streaming Assistant
  • Pico Link

On February 14, 2023, Pico announced support for OpenXR, but did not specify a release date
