Hi Pushpa,

No it can't be done and there isn't really a way to properly do it in
the first place, as the SNMPv3 protocol specification does not encrypt
the username when transmitted over the network.  It was never intended
to be a secret (unlike the security keys/passphrases which very much
are).

Your only other option is to use a different security backend transport
than USM (TLS, SSH, etc which aren't as widely supported unfortunately).
