You can set a custom filter in uBlock Origin to do this for you - here's an example filtering out Pinterest garbage:

google.##.g:has(a[href=".pinterest."]) google.##a[href=".pinterest."]:nth-ancestor(1)

Pinterest is an odd case. It's not quite like usual SEO spam because it's immensely useful for what it is (collecting images and links while planning stuff, art references, etc). But then they use whatever sneaky tactics they use to flood search, so people who aren't Pinterest users think it's garbage. Pinterest probably doesn't need to do this to rank highly since it's actually useful. I don't know what they're thinking.
