This problem can occur on any port that is available on NN and if it tries to access an entity resident on another dvr-routed subnet.

This issue can be addressed by explicitly blocking traffic from DHCP Servers to their respective default gateways in the NN.
But this may lead to problems when there is genuine need to allow traffic to/from other subnets to the DHCP Server.
Further to it, DVR has no presence in NNs today (unless it is also a Service Node). If we need to add rules, then all the l2-agents in the cloud must be configured to be DVR Capable.
