 - `CRIContainerLogRotation`: Enable container log rotation for cri container runtime.
 - `CSIBlockVolume`: Enable external CSI volume drivers to support block storage. See the [`csi` raw block volume support](/docs/concepts/storage/volumes/#csi-raw-block-volume-support) documentation for more details.

 - `MountPropagation`: Enable sharing volume mounted by one container to other containers or pods.
