How to make the enrollment window auto close after elections are made

Is it possible to close the enrollment window when the employee review and submit the enrollment. The requirement is that there should not be a re-visit option for the benefit elections once the employee chooses the benefit enrollment once. I tried testing with the Close Enrollment Period Date field by setting it to 'when elections are made', however, it still gives a pop up for the employee to confirm if the life event can be closed.

Is there any way to set up the enrollment window to auto close after making elections.
