This was first disabled on groovy, the first ubuntu release after focal:

root@g1:~# grep NFS /boot/config-5.8.0-59-generic |grep UDP
CONFIG_NFS_DISABLE_UDP_SUPPORT=y

The upstream help text next to that kernel option says:
"""
Choose Y here to disable the use of NFS over UDP. NFS over UDP
on modern networks (1Gb+) can lead to data corruption caused by
fragmentation during high loads.
"""

I'll leave it to the kernel team to comment further.
