Any advice for potato soup?

Basically the title, I want to make baked potato soup and while I have a good vegan cheese and sour cream I like to use in other soups, I’ve never tried making such a traditionally dairy heavy soup. I have tried a coconut based heavy cream substitute, but I found it to be a bit sweet. Is there a better heavy cream sub for a more savory flavor? Or maybe the brand I bought just happened to be sweet? Any advice is welcome!
