command line to change config

I want to uncheck the 'Connect through SSH tunnel' setting under Advanced Site Settings for all sites in a folder 'BSM". I know this command starts with WinSCP.exe /batchsettings.....but could someone provide the rest of the command?

This should do:

WinSCP.exe /batchsettings BSM/* Tunnel=0

Thank you very much, that worked and saved me a bunch of time.
