Avoid LAN devices in Unsecure Websites Report

My “Unsecure Websites Report” contains only devices on my LAN which do not support https. They have a LAN accessible only http admin interface.

Is there a way to prevent these devices from polluting my “Unsecure Websites Report”?

Could a URI with safe regular expressions fool the report into thinking the devices support https also (they don’t) and exclude them from the report?

Thanks for any even partial tips/solutions.
