These are available in Form libraries and users with "edit" permissions will see them. If users don't need to edit items, grant them "read-only" permission instead and those should go away.
If you are not hosting InfoPath forms than you don't need a form library. Use a document library/app instead and move your documents there - you should not see those links there.
It turns out you can remove those views. I have validated this works. After you have removed the "form" content type, you can open the list in SharePoint Designer (use the all files view), under the forms folder you will see
Remove those and your views will be gone from your dropdown as well.
They will be gone forever - even if you add the forms content type back at a later date. You would have to manually copy over those pages from a working library to get those views back.
