Places where IDV is referenced for blocking proctoring or displaying the IDV status to students and instructors should be removed. This includes the use of the ENABLE_INTEGRITY_SIGNATURE setting, which was used in part to deprecate IDV in those specified places. Other areas where ENABLE_INTEGRITY_SIGNATURE is used (such as for showing/hiding the integrity signature, for the verification deadline, or for certs) shall be left as is due to deprecation concerns.
