How set password in envoy

Hello, With laravel 5.7 app running envoy command I can set some parameters, like

envoy run Hostels2Deploy  --lardeployer_password=mypass 

and on any block I have to enter manually password. How can I use password parameter if in my envoy file I have

@setup
    $server_login_user= 'lardeployer';
    ...
@endsetup
    ...
    @servers(['dev' => $server_login_user.'@NN.NN.NN.NN'])

Thanks!
