Seems I have fallen behind with what can and can not be done regarding VR capability with a modded and possibly the stock version of IL-2 1946. I found a thread started in 2019, VR in IL-2 Sturmovik 1946 / BAT works! OMG! Meaning of life found!, over at Special Aircraft Service by UberDemon (Also danzigzag) detailing what needs to be done for it to work.
I have not tested it personally but UberDemon seemed to be pretty impressed with the results.
