I am new to this container world but I have started to dig in now. From NetApp blogs, it appears to me that in order to provide CVO(NFS) vol to the AKS/KS you will need a 'Provisioner'.
AKS = Cluster(Node=VM/Physical=Pods)
TRIDENT = Open Source Storage Provisioner
CVO = NFS vol
Have a look at this blog: Deploying Kubernetes with NFS volumes: (very basic)

I don't have anything setup yet, so I guess can only speculate theory at this moment. But, you could potentially engage NetApp cloud services team for any professional help if need be.
