I assume you are speaking of a Document Library's Name column right? If you have Nintex Forms you could edit the form with Nintex Mobile, double klick the name column and change the control mode to Display
This will render the name always as a label making it impossible to edit.
However, people could use the lists quick edit mode to still be able to edit the columns value. If you need to prevent this too you should disable quick edit in the document library settings.
