You can't run the reload like that. As far as I know there is a silent install option with command line arguments, but you can't do reload from command line. (It may be through API, but need to develop a solution by yourself).
If you are using server edition of Qlik Sense, you are able to set task in order to reload your application at QMC.
You can set daily, hourly, weekly so on... trigger, or with task event trigger you can make your task depend on other tasks.
