Remove Pages by Template

Was wondering if there is any ability to remove pages by page template server side. The code below shows an implementation that we attempted based on your filter_title_link filter.However, it still renders the HTML elements on the page for the removed items. Any help would be most appreciated. Thanks!

function filter_title_link( $title_link, $post_id ) {

$template_slug = get_page_template_slug($post_id);

if ( $template_slug === ‘page-test-template.php’) {
$template_link = ‘<span class=”template”></span>’;
$title_link = $template_link;
} else {
$title_link = $title_link;
}

return $title_link;
}
add_filter( ‘simple_sitemap_title_link_text’, ‘filter_title_link’, 10, 2 );
