Tell me, is it possible to monitor changes on sites that do not have rss? If tt-rss itself is not able to do this, then maybe there are selfhosted solutions that would generate rss feeds? The same rss-bridge cannot do this.
I have an XSLT based plugin that can do whatever you can imagine XSLT can do. One of the scripts out of the box “monitors” an HTML page and creates posts from each anchor link. Good for news site front page, gallery, etc… anything where a link indicates new content.
It should be rather simple to turn a single page into a post. Maybe adding a string hash to the guid, so if a page hashes the same TT-RSS guid checking would skip loading it again as new.
Is it possible to get this plugin? 
Yes of course. I meant to include this in my reply earlier:
XSLT plugin announcement (still incubating) - Themes and Plugins - Tiny Tiny RSS: Community
You’ll have to install php(version#)-xsl and libxslt to use xslt processors.
e. install php7 or php8, whichever version your containers/servers use.
