Change Notification Settings for Many Macs

Hello,

I have around fifty Macs that are running SEP for Mac version 12.1.4013.4013. Each time a user logs into a Mac, SEP presents a dialog box in the bottom corner of the screen, alerting them of a vulnerability BLOCKED. I can manually disable this setting via the Settings \ Network Threat protection \ Network Threat Protection Notifications slider, but going around to do so for fifty Macs is annoying. Is there a way to manipulate this setting from the terminal or through a PLIST file? I can't find anything to this extent in Symantec's documentation.

Thanks
