CSV links in Data Download section of Instructor tab in LMS don't expire if we're not using AWS

Description

In the LMS, in the Instructor tab and Data Download section, when generating a csv link, there is a message that says "To keep student data secure, you cannot save or email these links for direct access. Copies of links expire within 5 minutes."
https://github.com/edx/edx-platform/blob/master/lms/templates/instructor/instructor_dashboard_2/data_download.html#L103

But these links never expires.

Not sure if it is a bug or some kind of missed configuration.
