Read only Notebooks in a channel

Hi all,

while I am familiar with the concept of collaboration space and content library in the General channel, I'm not sure how to make a notebook added as a tab in a channel read only. I've tried to find the location of the notebook file in SharePoint, so that I can make it read only that way, but I couldn't find it 😞

This is a schools scenario, and we have a setup which has the class as the team, and subjects that class has as channels under that group. It would really make sense to have a way of making channel tabs read only.

Any ideas would be appreciated.
