Is there a way to clear DF-bit on Nexus 9k (rel 9.3.x)

In other words I am trying to make the nexus 9k to fragment the packets on last hop.
I realize by default PMTUD is enabled, but even when disabling it, it makes no different after restarting connections.
What I see is when a message is routed to my application and its mtu is larger than its mtu, the packets are dropped by the nx9k with df-bit set and the icmp unreachable (fragmentation needed) is returned back to the client. So I am trying to see if the nx9k can clear df0-bit and perhaps fragment rather than drop. Is this possible?

Have you tried using the show commands for the DF-bit and then find one that applies and type the no version of the command or commands

There is no such command that I know of... this is on Nexus9k.

You can be more specific if you know about it.
