It's not possible to either 
- create RWOP PVC
- Create RWOP clone
- Restore to RWOP PVC 
using 4.16.0/4.17.0 UI with ODF StorageClasses. 

Please see the attached print screen. 
The RWOP access mode should be added to all the relevant screens in the UI.     

    OCP 4.16.0 & 4.17.0
    ODF (OpenShift Data Foundation) 4.16.0 & 4.17.0

    1. Open UI, go to OperatorHub
    2. Install ODF, once installed refresh for ConsolePlugin to get populated
    3. Go to operand "StorageSystem" and create the CR using the custom UI (you can just keep on clicking "Next" with the default selected options, it will work well on AWS cluster)
    5. Wait for "ocs-storagecluster-cephfs" and "ocs-storagecluster-ceph-rbd" StorageClasses to get created by ODF operator
    6. Go to PVC creation page, try to create new PVC (using StorageClasses mentioned in step 5)
    7. Try to create clone
    8. Try to restore PVC to RWOP pvc from existing snapshot 
    

It's not possible to create RWOP PVC, not possible to create RWOP clone and to restore to RWOP PVC from a snapshot using 4.16.0 & 4.17.0 UI. 

It should be possible to create RWOP PVC, to create RWOP clone and to restore to a RWOP snapshot from PVC
