How to set integrity check exclusions in config.php

How do i set integrity check exclusions in config.php?
I know, I know, “that defeats the purpose of an integrity check!”…
My server instance modifies .htaccess & .user.ini , and creates php.ini to facilitate the system requirements of nextcloud.
I do not want to see a red alert in my dashboard unless there’s actually a problem, as the mentioned modifications are necessary.

Otherwise, how do I update what the integrity checker checks against? i.e.: have it check against a post-installation snapshot.
