What's more likely is a help desk tech will see the email, maybe ask their boss about it, and ultimately write back that there is no option to opt out. They're not going to provide you with more information, because that would limit their ability to do something in the future (especially since the person writing the response isn't a product manager or engineer and doesn't know anything about it anyway). It's worth a shot, if you don't mind the time to write a quick message; I'm just skeptical that anyone would actually pass the message up the chain that their legal boilerplate noone ever reads is vaguely unsettling.
