Removing the OOTB components from the design dialog/ Policy dialog.
Hello,
In Design dialog of the page, when author can see all the OOTB components along with Custom components. Similarly in editable template while adding the policy author can see all the OOTB components.
Classic Design dialog :

Editable template policy:

Is there a way to hide/remove those components and show only custom components.
Thanks,
Meenakshi
