Hi Rosalin
You are right that there is no equivalent mechanism for controlling the visibility of orders to customers. The closest thing I can think of is the TMF672 User Roles & Permissions API which can support RBAC on any kind of entity, including orders. Alternatively go ahead and add a new concrete field to the order (using the polymorphism pattern), perhaps even raise a JIRA with TM Forum.
Good luck!
Dan.
