NoAutoRebootWithLoggedOffUsers - Windows Server OS
Considering the server availability, we administrators are not getting downtime as we desired. So, Microsoft should give the support for server OS to prevent the reboot the server in logged-off mode after windows update installation. I have a suggestion that I'm giving below. If it is possible, it is very helpful to the world of Windows administrators. Add the registry value in server at least in all available server operating systems

Even I am facing this issue in my organization.

Ultimately, we need not to reboot the server automatically, if nobody logged on the server, after windows update.
