Hi @ManasaKandula! Welcome to Canvas and to the Canvas Community! Since you posted this in the Canvas Commons Discussion area, I'm wondering if this is about Commons or Canvas LMS. I suspect you are using Modules in Canvas, and they are usually visible to students when they are published. However, you can leave a module unpublished and therefore hidden from students. You can also lock the module until a certain date. Here are some guides on these topics:
How do I publish or unpublish a module as an instructor?
How do I lock a module?
I hope this helps, but let us know if you need more information.
