Yes. Below is a list of command line switches available for Sync on Windows. One can get the list also by starting Sync with the switch /help.
/config <config_name>
Starts Sync in configuration mode.
/webui
Forces Sync to open web interface in the default browser. Note that Sync will only listen on the loopback interface and won’t allow connections from other computers. If you want to allow connections from other computers, also use /config and allow WebUI to listen on other interfaces.
/storage <storage_path>
Forces Sync to place/look for the Sync Storage Folder at a user defined location.
/noinstall
Runs Sync without installation. Sync will not install itself and will use the default storage directory (%appdata%\Resilio Sync).
/S
'Silent' start (no program interface will be displayed).
/performinstall
Runs Sync installer which will show installation wizard and install Sync to the Program Files folder as well as create a default storage path.
/minimized
Forces Sync to not show UI window. It will still be accessible from system tray.
