Hello,

Please create the Empty Header where you want to disable the header on the page . Then set this header in the page options:

You can disable the footer section using the option provided by our theme when you edit your page in Dashboard > Pages > Edit Page > In the bottom of the page settings disable the footer.

Best Regards.
