Tested that if a pvc is specified and the pv is provisioned by DO CSI, the volume is considered as a dobs volume and it's ownership is checked. Since our csi driver supports only persistent storage, specified a csi driver directly in the pod spec results in an error. However, leaving that as is if we change that in future versions.
