Hi rioma,

The comment form is purely a wordpress feature. You can disable it on all pages individually by opening up the page (or post) editor.
In the editor, scroll up to the top and open up your screen options in the top right corner. Make sure that the [] discussion box is checked.
Next scroll down past your post/page options until you see the discussion section. You can there uncheck the box that says “allow comments”

Kind regards,
Kevin
