Berlin Theme -> Can browse tabs be disabled/removed in an exhibit?

Using the Berlin Theme for an Exhibit. The option to ‘enable site-wide search’ is not checked, but the top menu tabs to browse/search items, collections and exhibits are still active.

I want the public view of the exhibit to be limited to the exhibit items and not provide a gateway to our entire public item list. Is there a fix for this? A different theme?

Figured it out: Commenting out the public-nav-main references in the header.php and footer.php files seems to work.
