Add this to your functions.php:
add_action('admin_head', 'remove_metaboxes_for_non_admin');
function remove_metaboxes_for_non_admin(){
if (!is_admin()){ // only remove for non admins
remove_meta_box('wpseo_meta', 'post', 'normal'); // removes the wordpress seo by yoast metabox from posts
remove_meta_box('wpseo_meta', 'page', 'normal'); // removes the wordpress seo by yoast metabox from pages
// continue adding as necessary
}
}
See here for remove_meta_box reference.
You can find the “ids” of the metaboxes by inspecting the code to see what the id is for the div wrapping the box.
