How to set SEP 12 services to Disabled from Services.msc

Hello,

Is there any way to set "Symantec Endpoint Protection" service in SEP 12 to Disabled? Since SMC (Startup type Manual) is dependant on SepMasterService, we don't need to do anything with SMC, only to set SEP service to Disabled.

I tried with the below commands but they don't work for me:

sc stop "SepMasterService"
sc config "SepMasterService" start= disabled

Tamper protection is disabled, I am logged in on the machine as Administrator.

In SEP 11, both SEP and SMC services can be set to Disabled easily from services.msc. I know that with a policy from the SEPM we can enable the option for "Disable Symantec Endpoint Protection" or to unlock the "Enable Auto-Protect" option, but if there is another way will be good to see it.
