Create pods using only ephemeral storage (No PVC)

I am looking to create a cluster that uses only ephemeral storage without creating PVC's. Is this possible with the current operator? I am able to use local storage PVC's but those seem to cause reassignment issues during node failure. Would be nice to skip all that and just use ephemeral local storage.

EDIT: Would also be nice to have a timeout on PVC when the pod is pending. I'm using a spot node group and nodes can be recreated in different AZs, causing PVCs to become inaccessible.

No files, tests, or entry points are named. Start by locating how the operator configures PVCs for pods and handles pods pending on storage, then determine whether ephemeral storage and a PVC timeout are supported requirements. Done would require an agreed design and documented behavior for both cases.
