Only using NFSv2 and/or NFSv3 disabling NFS via TCP

[Peronia]

Describe the bug

When you only use NFSv2 and/or v3, NFS over TCP is disabled. When you active NFS4 or higher, it gets enabled.

To Reproduce

Steps to reproduce the behavior:

1. Active only NFSv3 via OMV interface
2. Try to mount it over TCP -> won't work
3. Enable NFSv4 (or higher) or enable tcp in /etc/nfs.conf.d/99-openmediavault.conf and restart nfs-kernel-server with sudo systemctl restart nfs-kernel-server
4. Try again to mount it, it now should work

Expected behavior

Since NFSv2 and v3 supports TCP, why not enabling it?

Additional context

As you can read in the forum, it is not possible for me to mount the NFS share via UDP when TCP is off. However, other users seem to be able to do this.

Any news here? I must change the file manually once again.
