LTI 1.3 grade syncs can (and will) push a grade to Canvas regardless of it's due date in Canvas. This should be optional/controlled in canvas if a due date has passed. Additionally, for various reasons, a "Teacher" may want to lock a grade or assign a manual grade that prevents anything (e.g., LTI grade) from automatically changing the grade BEFORE a due date. Without the ability to block an auto grade sync from a 3rd party tool in either scenario, the student has control of the grade via the LTI tool.
Develop an option to control 3rd party grade syncs from the Canvas side at the activity level settings or grade settings somewhere in canvas.
