[Nova]ask for help: how to plug vif to ovs when ovs is not together with nova-compute

hello， I encountered some problems in deploying the smart network interface card（SmartNIC）where Nova-compute is not together with OVS. For example, OVS is deployed on the SmartNIC and Nova-compute is on the Host(Compute Node), how does Nova plug the virtual interface of VM to OVS bridge? Does the latest version of openstack support this? Thanks.
