Whiteboard acces only for moderators

First of all I wanna tell that I've been using RingCentral Video for 2 years instead of Zoom and it's pretty amazing. ;)

My question: can I block acces to write on whiteboard only for moderators and admins? I can't find this option - can do it for screen sharing and writing on the chat but not for the whiteboard. Is it possible? If not, can you consider implementing option like this?
