Можно ли сделать метод невидимым только для наследника?

$container = new Container();
 
$app = new App($container);
 
$app->get('/', ExampleAction::class); // RouteCollector::get
 
$app->run();

class App extends RouteCollector
{
    private array $middleware = [];
 
    public function __construct(
        private readonly ContainerInterface $container
    )
    {
    }
 
    public function getContainer(): ContainerInterface
    {
        return $this->container;
    }
 
    public function run(): void
    {
        $request = new Request();
 
        $router = new Router($this); // хотел чтобы RouteCollector::getRoutes был виден только внутри Router :)
 
        $routeResult = $router->matchRoutes($request);
 
        foreach ($routeResult->getMiddleware() as $middleware) {
            $this->addMiddleware($middleware);
        }
 
        $handler = new Handler($routeResult, $this->container);
 
        $kernel = new Kernel($handler, $this->middleware);
 
        $response = $kernel->handle($request);
 
        $response->send();
    }
 
    public function addMiddleware(string $middleware): void
    {
        $this->middleware[] = $this->container->get($middleware);
    }
}

class App
{
    public function __construct(
        private Router $router
    )
    {
    }
 
    public function get($path, $handler)
    {
        $this->router->get($path, $handler);
    }
 
    public function post($path, $handler)
    {

    }
}
