no tag-switching ip propagate-ttl forwarded - this command we use generally for MPLS.
if you looking traditional then you need to block Type 3 echo ICMP i guess- never tested.

Easiest way I see is to configure IP access-lists, which blocks ICMP or UDP/PORT 334xx destined to the SVI, and apply that RACL on the SVI ingress. However, I would recommend not to do that, because it will remove some capability to troubleshoot on your Nexus switch. In the end Nexus is not a firewall, it's a L3 Switch.
