symantec endpoint protection cloud uninstall

We'd usually use GPO or SCCM or something along those lines, we use software which allows us to send scripts through to machines so anything that we can script or a workaround would be appreciated. We're needing an automatic way of removing this software from our machines without user intervention. I've tried to use WMI call Uninstall for Symantec, but SEPC isn't listed.I've tried to ProcessMonitor the uninstaller - no luck there.I've tried to decode the InstStub.exe (worrying stuff in this file btw.).I've tried every switch I can think of with the InstStub.exe file (the uninstaller file) and had no success.I've tried the NRT tool - this can't be run silently.I've tried the CleanWipe, SepPrep and CEDAR tool - this can be run silently but these open the InstStub.exe.I'll detail below the steps I've already tried: Symantec offers mass uninstalls on their other products which wouldn't be the case if it was a security risk.

According to the official KB mass uninstallation is considered a security risk, however this is simply not true.
