Wie kann ich die NavigationLoaderInterface's $depth ändern?

Ich möchte die NavigationLoaderInterface oder NavigationLoader $depth zu 10 ändern
aber ich kann die Services nicht decorieren.

kann jemand mir helfen?

<?php declare(strict_types=1);

namespace Shopware\Core\Content\Category\Service;

use Shopware\Core\Content\Category\Tree\Tree;
use Shopware\Core\System\Annotation\Concept\ExtensionPattern\Decoratable;
use Shopware\Core\System\SalesChannel\SalesChannelContext;

 * @Decoratable()
interface NavigationLoaderInterface
     * Returns the first two levels of the category tree, as well as all parents of the active category
     * and the active categories first level of children.
     * The provided active id will be marked as selected
    public function load(string $activeId, SalesChannelContext $context, string $rootId, int $depth = 2): Tree;
