Excluding category posts from certain page

Hello
I have a landing page and my latest posts are on another page called “Latest News”, with ID=10837. I am trying to exclude all posts from category #11 from being displayed on this page. Is this the correct code as it doesn’t seem to work at all, it is in functions.php in the child theme folder

function exclude_category( $query ) {
if ( is_page( 10837 ) ) {
$query->set( ‘cat’, ‘-11 );
}
}
add_action( ‘pre_get_posts’, ‘exclude_category’ );
