What physical ports on unity are needed to use NFS with Unity CSI driver ?

I would like to setup the CSI driver to use NFS volumes on NAS shares on the Unity. 

Currently I don't have iSCSI ports on our array. Is this a requirement? From below it seems to be that to use NFS iSCSI ports are a requirement ?

Requirements

• Install Kubernetes or OpenShift 
• Configure Docker service
• Install Helm v3
• To use FC protocol, host must be zoned with Unity array
• To use iSCSI and NFS protocol, iSCSI initiator and NFS utility packages need to be installed
