can you add vr to xbox one x

The Xbox One S was never mentioned for VR gameplay.

When they first announced the more powerful Xbox One X, they mentioned, it would be powerful enough for VR, but didn't mention which VR hardware would be compatible with Xbox.

Then, shortly before the Xbox One X was launched, the VR feature was removed from any marketing materials.

I own the Oculus Rift, and I can confirm that it does NOT work on the Xbox One X (or any other Xbox One for that matter).

So short answer: No you can NOT use Oculus Rift on the Xbox One at all.

Xbox Head Phil Spencer gave this interview, specifically about VR:

It is an interesting read, basically, the Xbox One X is capable, but they do not see the current state of VR/MR being in line with what they want for the "Family Room" type of arena that the Xbox plays in.

I thought that VR was going to be a major feature of the Xbox One X (while it was still in development as "Project Scorpio"), but this is not the case... for now, at least.

Currently, there's no VR headsets, accessories, or support available on the Xbox One X. As far as I know, there
aren't any hints or plans on bringing VR to Xbox any time soon.

I love it. Adds more to gaming as a whole. I would love for Xbox to come out of nowhere at E3 with a VR to release with the Series X.

That Idea would be fantastic. The connect would be a great way to enhance a VR experience. Since it can sense moment it may be able to sync with a VR headset to make it much better to play. It's not needed though.

Xbox should have VR capability with project scarlet since it will be more powerful than the One X. It would be a great achievement to bring VR to all Xbox fans.
