Using Symfony 5.4 combining lexik/jwt with remote auth together - rest

Question

I need to make proxy pass application with jwt auth.
User storage server is also in another location. The question is - how to combine it together?
My input method is json; for now I'm using native configuration:
login:
pattern: ^/api/login
stateless: true
json_login:
check_path: /api/login_check # or api_login_check as defined in config/routes.yaml
success_handler: lexik_jwt_authentication.handler.authentication_success
failure_handler: lexik_jwt_authentication.handler.authentication_failure
provider: app_user_provider
custom_authenticators:
- App\Security\Guard\Authenticator
I made own Authenticator which makes API REST Request and returns User object.
Than I thought, I need make own Passport and Badge class to force passing User Entity without password validation:
public function authenticate(Request $request): Passport
{
$data = json_decode($request->getContent());
if( !isset($data->username) || !isset($data->password))
throw new CustomUserMessageAuthenticationException('No API token provided');
$result = $this->remoteAuth->getUser($data->username, $data->password);
//return new SelfValidatingPassport(new UserBadge($data->username));
$result->setPassword($data->password);
$pass = new RemotePassport(new RemoteBadge($result));
return $pass;
}
Unfortunately, while my authenticator works fine, but then another native Symfony native JsonAuhenticator comes as a second, and returns password verification exception.
Can you tell me, how to handle it? How to disable this another checking? Should I make own loginAction? Somehow disable native checker on Content-Type: application/json? Please help.
