You should have your ARDK support the Vive XR Elite. Since the Vive XR Elite has a depth sensor on it, ARDK could really take advantage of Vive XR Elite’s depth sensor to provide some precise spatial meshing like it does on iPhone devices with a LIDAR sensor.
Ardk uses arcore and arkit. Afaik no HMD supports that, so it won’t work
As Dylan noted, since head mounted displays currently don’t support ARCore or ARKit, support for them wouldn’t be possible. Sorry for the inconvenience
