In this section https://docs.redhat.com/en/documentation/red_hat_openstack_platform/17.1/html/configuring_network_functions_virtualization/config-sriov-deploy_rhosp-nfv#create-nic-config-template-sriov_dplsriov-nfv

We give an example of an SRIOV PF with 16 VFs:

- type: sriov_pf
  name: enp196s0f0np0
  mtu: 9000
  numvfs: 16
  use_dhcp: false
  defroute: false
  nm_controlled: true
  hotplug: true
  promisc: false

There is no reason to keep nm_controlled: true. On the contrary, it may cause issues if that device is not involved in host traffic (management network). It should be excluded from network manager control.
