The short answer is no. The long answer is that you can require users to
have valid kerberos credentials for access to an NFS volume (via v3 or v4).
But that requires the setup of Kerberos and I'm not volunteering to help
with that.:-) There are some good books/tutorials on setting up Kerberos
and it works well, once you wade through the hassles of getting it going.
(Kerberos authenticates the user for access to the server volume. It is
 not a host based authentication for the mount. If you choose to use
 Kerberos, you need to allow the user to do the mount without sudo by
 setting vfs.usermount=1 and then you restrict the server volume(s) with
 the sec= export option.)
