The following files have to be patched:

• /mmonit-4.3.1/bin/mmonit using the m/monit patch, this will be sufficient to make m/monit never expire even though an expiry date will be shown (just use date on Linux to forward the date to a date in the future to check, we tested with a few years),
• /mmonit-4.3.1/docroot/admin/general/index.csp with the index.csp patch in order to remove the "License" section entirely. It is advised to apply this patch only after testing the expiry date to make sure that the mmonit patch works, and only then apply this patch to just embellish the interface.
