Not really
I bought a “corporate” level laptop from Lenovo because I needed something durable and they offer a great warranty. My laptop thus came with AMT even though I’m my own IT department. So no, not every user that has AMT has a corporate IT department to set it up.
To add insult to injury, it comes loaded with Intel software that tells me that AMT is enabled and secure mode is disabled, but no option in said software to toggle either one!
