What you expected to happen: Is there any way that can let nmstate ignore the devices which it doesn't know? I don't want to any ops on those OVS device.

How to reproduce it (as minimally and precisely as possible): Run kuberenetes-nmstate on a cluster that using kube-ovn cni

Anything else we need to know?: Execute command "nmstatectl show" on the node gets the same error.

Environment:

kubernetes-nmstate image (use kubectl get pods --all-namespaces -l app=kubernetes-nmstate -o jsonpath='{.items[0].spec.containers[0].image}'): quay.io/nmstate/kubernetes-nmstate-handler:latest
NetworkManager version (use nmcli --version)
Kubernetes version (use kubectl version):v1.28.6
OS (e.g. from /etc/os-release): Ubuntu 22.04 5.15.0-112-generic
Others: kube-ovn:v1.12.14
