Unless you use Kerberized mounts (sec=krb5 or sec=krb5i or sec=krb5p), no.

I, personally, think that a simple authentication mechanism that had a
name instead of uid in it would be nice. However, to have any chance of
getting that through the ietf working group, I think it would have to be
accompanied by some sort of host based security (think "like an ssh tunnel
using IPSEC") and I don't have the time nor expertise to work that all out.
Then, it all has to be written up as an internet draft, and then, since I
don't have any travel budget to go to the IETF meetings, I'll bet it'd never
get anywhere.

If some NFS vendor likes this idea, I'd be happy to work wth them on it,
because I believe setting up Kerberos is just too much hassle for most
