Thanks for your posting on Q&A.
I totally understand your concern and we're very sorry for any inconvenience that may caused. It is product design and it's out of my control. The design concept of the Windows is that the customers could install and apply the essential updates as soon as possible. Please review this link to learn more about Windows as a service.
In addition, we could enable the other policies to delay automatic reboot. Please review this link to apply the Turn off auto-restart for updates during active hours and No auto-restart with logged on users for scheduled automatic updates installations policies to delay automatic reboot.
Please keep us in touch if there are any questions of the thread. Hope the above will be helpful. Have a nice day :)
Regards,
Rita
