Hi,
You can achieve this using overlay.
1. Overlay the node which you want to modify e.g. /libs/dam/gui/content/assets/jcr:content/actions/selection/create
2. modify privileges property in below node to add privilege which your creative users won't have e.g. jcr:readAccessControl
/apps/dam/gui/content/assets/jcr:content/actions/selection/create/granite:rendercondition/privilege
I think, this should work.
For more details find below
