Does vsphere 6.5 support File VVol on NFSv4.1?

Question as tile.

We have an implementation on File VVol NFSv3. And I found some document mentioned that the NFSv4.1 is available for vsphere 6.5 for file vvol

But Is there any existing, or on going, implementation that based on the vsphere 6.5 File VVol NFSv4.1 feature? And is there any official document for enabling them from the VASA API implementation and data path implementation.

Thanks
