How can i resolve Dynamic pages issue in my shopify website

I’ve noticed that over the past two months, Google has been indexing multiple versions of my main collection page. For example, my main page is example.com/collection/kitchen-tile, but Google is also indexing similar pages like example.com/collection/kitchen-tile?dfhpage1, example.com/collection/kitchen-tile?dfhpage2, and so on. Why is this happening, how can I fix it, and is it harmful to my SEO ranking?
