Hi,
You would need to do:
# system host-label-assign controller-0 sriovdp=enabled
# system host-if-modify controller-0 <interface> -c pci-sriov -n sriov0 -N
<num vfs>
# system interface-datanetwork-assign controller-0 <interface>
<datanetwork>
# system host-unlock
And that should populate the /etc/pcidp/config.json
