XFS seems to be good for hyperdisk:

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: hyperdisk-xfs
provisioner: pd.csi.storage.gke.io
parameters:
  type: hyperdisk-balanced # Or hyperdisk-extreme, hyperdisk-throughput, hyperdisk-ml
  csi.storage.k8s.io/fstype: xfs
reclaimPolicy: Delete
volumeBindingMode: WaitForFirstConsumer

Node Pool creation already works since 7c59ae5
Next step is to create the storage class.

I had to add a taint to the node pool to ensure no workloads get scheduled on it non-Hyperdisk PVCs: hyperdisk=required:NoSchedule
I plan to make the taint a configuration property of the Makefile
