/**
 * Remove status message.
 */
function remove_status_message(string $type, callable $callback): bool {
  $messenger = \Drupal::messenger();
  $messages_by_type = $messenger->messagesByType($type);
  $message_deleted = FALSE;

  foreach ($messages_by_type as $message_key => $message) {
    if ($callback($message)) {
      unset($messages_by_type[$message_key]);
      $message_deleted = TRUE;
    }
  }

  if ($message_deleted) {
    $messenger->deleteByType($type);

    foreach ($messages_by_type as $message) {
      $messenger->addMessage($message, $type);
    }
  }

  return $message_deleted;
}

Использование:

remove_status_message('error', fn($message) => preg_match('/^Обнаружен. \d+ ошиб/u', (string)$message));
