Hide posts that belong to a certain category from the post navigation links

I am currently hiding posts that belong to a certain category from the blog page by using the following code:

add_filter('pre_get_posts', 'excludeCat');
function excludeCat($query) {
      if ( $query->is_home ) {
            $query->set('cat', '-45');
      }
      return $query;
}

Is there a way to add to the query to also hide the posts from the post navigation links so that they don't get displayed either?
