Not sure about OpenXR as default runtime with VD, but for Airlink you have to set it, yeah.
After that, with airlink, I usually just use desktop version of steam (either through actual or virtual monitor) and press Play, if there are multiple runtimes available, the game usually lets you choose.
Don't know specifics with VD, because I don't use it myself.
