dns probe failed, need to disable dns check

What happened: When applying

apiVersion: nmstate.io/v1
kind: NodeNetworkConfigurationPolicy
metadata:
  name: vpc-mgmt-v100
spec:
  nodeSelector:
    networkmanager: "true"
    kubernetes.io/hostname: vmaas-worker2
  desiredState:
    interfaces:
    - name: "vpc-mgmt-v100"
      type: vlan
      state: up
      mac-address: 02:b0:ad:33:bb:98
      vlan:
        id: 100
        base-iface: bond0
      ipv4:
        dhcp: false
        enabled: false

nncp sits for a while with no status and nnce says ConfigurationProgressing

When I look at the nmstate-handler pod I see it fails for DNS check

{"level":"error","ts":"2023-04-03T19:34:49.252Z","logger":"probe","msg":"failed checking DNS connectivity","error":"[lookup root-server.net on <redacted_ip>:53: no such host lookup root-server.net on<redacted_ip>:53: no such host lookup root-server.net on <redacted_ip>:53:  ....

Also what is root-server.net ?? It's also hardcoded in kubernetes-nmstate/pkg/probe/probes.go

What you expected to happen: nmstate to not check dns probe if we don't want it to (or let me know how to get around this problem).

How to reproduce it (as minimally and precisely as possible): See above
