410 instead of 404

Hi, how can i change the behavior in Enfold, that when a link is incorrect, the code 404 (and the search option) is displayed. I want to sent back the code 410 instead, that the site is deleted.

I have set up customer pages for 401,403,404,410 and 500 and linked them in the .htaccess already. I the Enfold Child Theme options i can say “No custom site” then the 404 site appaers from inside the theme with a search fild. Otherwise i can set to “custom” page, then i can select one. But the Status code (for google, etc.) is 404.

How can i tell enfold, to sent 410 if a page doesn´t exist?
