Simulator - start from command line without command window

Is that somehow possible?

I do run some automatic tests on my watchface and therefore I want to hide the command line window that opens up when I start the SIM. Is it possible to pass some arguments to the exe file so that the command line window does not show up? It's mentioned here (https://developer.garmin.com/connect-iq/connect-iq-basics/getting-started/) but there is no information about possible arguments...

If the sim is started from Eclipse / Visual Studio it does not show the command line window...
