They addressed this in their FAQ:

Skyrim VR?:

• The most recent Skyrim VR version is currently on the pre-anniversary update of Skyrim and thus is incompatible with Skyblivion through normal means.
• A community-made VR patch mod would have to be installed for Skyblivion to boot properly. Regardless, there will be no official support for Skyrim VR at this time.

It’s not impossible and modders will likely jump at the opportunity the moment Skyblivion releases, but nobody can tell how long it would take to implement proper VR support.
