Restricting access to Factory Content Folders within Shared Folder for Employee role

Content

Hi All,

We need to restrict view of seeded folders within Shared Folders but it is giving error as 'The seeded content are locked as part of the factory content lock down feature.. All the customizations should be saved under "Shared/Custom".

Can you suggest some workaround so that employee don't see these folders? We are giving access to employee for viewing certain Learn Reports and Dashboards, so if he click on Catalog on top part of the page then he can reach the shared folders which we want to restrict.
