Thank you for posting your question in the Microsoft Q&A forum.
The behavior you're describing: where OneNote pages attached to a Teams assignment become read-only after students click Turn in is currently by design in Microsoft Teams for Education. This locking mechanism helps ensure that submitted work remains unchanged for grading purposes. Unfortunately, there is no built-in option to turn off this feature in Teams or Class Notebook settings.
I completely understand how this automatic page-locking can become a real challenge in day-to-day teaching. When students want to go back and make corrections or continue working after submitting, having to manually unlock each page or ask them to "unhand in" the assignment can be time-consuming and disruptive to the learning flow. A more flexible option to manage this behavior would genuinely help educators like yourself support student growth more efficiently, especially in environments that encourage iterative learning and feedback.
