new whiteboard- restricting ability to edit/share

Hello ZOOM:  I am an admin and have a group of ZOOM Enterprise Pro hosts who have created whiteboard "templates" in order to facilitate certain group activities.  Is there a way to prevent participants from accidentally erasing or editing elements of the whiteboard template itself (or, for that matter, other participants' contributions) - while still allowing them to add/edit/delete their own contributions?  Second, can we prevent participants from further sharing whiteboard with anyone other than who the host has designated when they shared?  Thank you!
