NFS persistent volume without hard-coded storage?

Cluster information:

Kubernetes version: k3s v1.23.6+k3s1
Cloud being used: bare-metal
Installation method: k3s/curl
Host OS: AlmaLinux 8
CNI and version: ?
CRI and version: ?

k8s’s documentation on NFS PVs doesn’t actually list all of the expected/required/optional parameters. It links to an example, which itself doesn’t seem to list them out.

All of the examples I’m finding seem to declare a hard limit on the NFS volume’s storage capacity. Is it possible not to declare that limit, or is there some reason k8s requires it?

Thank you!
