Unity XT380 NFS v4 and VVOL

Hello,

I'm in the process of setting up a new environment with vSphere 7.0 U3 and a Unity XT380 VVOLs using NFS v4. However, when I enabled the VVOL feature in the NAS server in Unity, I had to select NFSv3. Although I also checked NFSv4, the vvol datastore is only being presented to the ESXi servers using NFSv3.

I'm looking for guidance on how to configure the system to use NFSv4 instead of NFSv3. Any insights or advice on this matter would be greatly appreciated.

Thanks in advance,

Andy
