I'm configuring my network so it does not advertise all of my /30 subnets used for WAN tunnels. These IPs do not need to be routed and simply flood the OSPF LSA database.
This is easy to do on IOS and IOS-XE, but is there something in NX-OS that can do something similar to "ip ospf prefix-suppression" for a specific interface?

In IOS it was bit easy, try running some question marks under address family IPV4 on OSPF.

Under the interface config, I don't see anything that's similar:
NX(config-if)# ip ospf ?
authentication Authentication on the interface
authentication-key Configure the authentication key for the interface
cost Cost associated with interface
dead-interval Dead interval
hello-interval Hello interval
message-digest-key Message digest authentication password (key)
mtu-ignore Disable OSPF MTU mismatch detection
network Network type
passive-interface Suppress routing updates on the interface
priority Router priority
retransmit-interval Packet retransmission interval
shutdown Shutdown ospf on this interface
transmit-delay Packet transmission delay
I even looked under the "router ospf" config and there isn't much there, either.

EDIT - due to typo
ip ospf prefix-suppression - this command still valid i guess never tried, we will test over weekend if i get chance.
