In the left menu dropdowns, look for Remove URLs where you can remove URLs or even directories that you do not want indexed - but you need to read their requirements. The URLs do need to exist on your site in order to remove them from indexing, they should be noindexed but NOT blocked in robots.txt.
So if you are deleting, moving or renaming those pages, a redirect would be better. The URL parameters settings is not for removing indexed pages from searches.
