Hi @loysenk 

That would be a great feature, to limit module access based on section, but it's not currently possible.  The options for limiting access to a particular module is to "Lock" it and keep it from opening until a particular date, or by setting a prerequisite to the module that requires that another module be completed first (https://community.canvaslms.com/t5/Instructor-Guide/How-do-I-add-prerequisites-to-a-module/ta-p/1123 ).
