@lucpestille for that I think you would need to use the SEO hook for modifying the post title, but you’ll need to do a bit more checking

add_filter('wpseo_title', 'change_seo_title');
function change_seo_title($string) {
  $queried_object = get_queried_object();
  if (!isset($queried_object->ID || 
      get_post_type($queried_object->ID) != 'your-post-type-here')) {
    // bail early
    return $string;
  }
  $related_post = get_field('post_object_field_name', $queried_object->ID);
  if ($related_post) {
    $title = get_the_title($related_post->ID);
    $string .= ' - '.$title;
  }
  return $title;
}
