Revoke Modify (INSERT UPDATE Delete Truncate) on a table Cassandra DSE

Question

I have users that I do not want them to truncate from a table in DSE, I used revoke MODIFY on ALL KEYSPACES from USER; I even used Restrict but still, the user can truncate. Is there anything I am missing ? is there any setting in Cassandra.yaml? The command I used to see all the permissions granted or revoked on a user is List all of user; or SELECT role, resource, restricted FROM system_auth.role_permissions WHERE role = 'user'; I would create a role and restrict truncation but they still ca truncate. screen shot of the list all of the user
