How to install lazy load for League\Flysystem\Adapter\Local service?

Question

symfony

Hey!
Please tell me how to solve this problem correctly.
Symfony 5.0, dev env, package 1up-lab/OneupFlysystemBundle .
I want to set lazy loading for League\Flysystem\Adapter\Local, but it doesn't work.
Checking class_implements($filesystem) doesn't show proxy interfaces, checking via bin/console debug:container doesn't change anything either.

#config/services.yaml
services:
    _defaults:
        autowire: true
        autoconfigure: true
        bind:
            $filesystem: '@oneup_flysystem.local_filesystem_adapter'
    #other stuff
    League\Flysystem\Adapter\Local:
        lazy: true

Installed symfony/proxy-manager-bridge and ocramius/proxy-manager in advance, cleaned var/cache.
Different configuration options give errors:
- replacing a class with an alias:

The definition for "oneup_flysystem.local_filesystem_adapter" has no class. If you intend to inject this service dynamically at runtime, please mark it as synthetic=true. If this is an abstract definition solely used by child definitions, please add abstract=true, otherwise specify a class to get rid of this error.

- adding an alias to class parameters:

The configuration key "lazy" is unsupported for the service "League\Flysystem\Adapter\Local" which is defined as an alias in "/app/config/services.yaml". Allowed configuration keys for service ali  
  ases are "alias", "public" and "deprecated" in /app/config/services.yaml (which is loaded in resource "/app/config/services.yaml").

I understand that I'm setting up the service incorrectly, but I'm confused about which side to approach it from.

// App\Kernel
protected function configureContainer(ContainerBuilder $container, LoaderInterface $loader): void
{
    // ...
    $container->addCompilerPass(new class implements CompilerPassInterface {
        public function process(ContainerBuilder $container)
        {
            $container->getDefinition('oneup_flysystem.adapter.local')->setLazy(true);
        }
    });
}
