How to remove site certificate in Safari?

Question

macOS

In general, such a situation, someone threw off a link to the site with https, but the site still does not know how to properly interact with its service servers, so some internal connections do not go through (the request goes to them via http).
From here there are conflicts, etc. It just doesn’t work to enter the address without httpS, it throws it back to https.
