Yes. Corporate IT will install extra software on the machine which does this kind of thing.
On the macs, there's an auto-updater which forces a restart with a countdown, no way to stop it. Its not by Apple for sure, based on how jankey it looks, but terminating the process will prevent the restart. The worst is spyware which randomly spins up one of the CPUs to 100% for 10 mins every few hours while it runs du.
We get updates through a corporate AppStore and they function like normal Apple updates. I can choose when to install, etc. I found the software underneath (https://www.jamf.com/solutions/technologies/mac-management/). Sounds like a better UX than what you got stuck with.
The spyware on my personal phone so that I can read corporate email is pretty asinine though.
