Boot Time Protection Freezing System - How to disable through Safe Mode or CLI?

Hi there,

 

I noticed that since enabling Boot Time Protection (Setting: Normal) for my PC, it freezes during logon when the profile is loading. I can manage to log in to Safe Mode (and Safe Mode w/ Networking) just fine, but Norton (NIS.exe) will not start up due to the system being in Safe Mode.

 

Since I can't access NIS' settings to disable Boot Time Protection through the GUI, how can I disable the setting while in Safe Mode?

 

Thanks.
