Fix general RSS feed to block certain tag (abandoned)

Instead of a custom RSS for a particular tag, I want my regular RSS to NOT contain a particular tag.

I’ve read the RSS docs, and they seem to be focused on setting up an RSS feed for podcasts, for example.

I assume there is something simple I can do in Routes.yaml to accomplish this, without having to build a new template and such. Thoughts?

Any thoughts? All the docs I’ve read are about adding a new RSS feed. I have one, it works fine, and it’s being used in multiple places. All I want to do is block certain posts from going out via RSS. Is there some simple way of doing this, using a tag (for example)?
