Yeah, the trick is to do your own curation and go from there.

If you like some authors or journalists or bloggers, go see who they read (trust me they all say who they follow in their own niches) and build from there. You can develop quite a good RSS feed following this method in like an hours tops.

You can ban a domain from search results with Kagi

You you can bend a handful with duck duck go as well. However, it's only a handful and you run out and you're stuck.
