It is possible

Whether when game is started it searches is started dedicated server namely process battlefront.exe

And if game finds this process started that is not started

Means it is necessary to hide simply battlefront.exe

For this purpose it is possible to use the hacker utility for hide of processes HideToolz (http://www.wasm.ru/baixado.php?mode=tool&id=390)

We start the dedicated server
Then start the utility and it is found in the list of processes battlefront.exe , it is hidden it

Now we can start game and play on the our server

sorry for bad English
