How to remove Category icons in iOS 18.2 Mail?

With 18.2 introduction of category inboxes in apple mail, even when selecting list view (top three dots in mail app) to return it to the old format, you still have the annoying new icons representing the categories in front of each email. I'm selecting 'list view' because I don't want to use 'categories' at all. Can the icons be removed from list view so that I can just see a normal/clean email inbox?
