The course start date and course end date come though automatically for provisioned courses. Courses will automatically open and close on those date and times.
NOTE: You cannot change the start date and end date of your provisioned courses in Moodle. This can only be done to courses in your staging area.
If you’d like to hide an provisioned course that was created for you but will be unused, you’ll need to hide the course from students the day AFTER the start date or you can also un-hide the course the day AFTER the end date of the course.
