Can I make Windows Update install updates but defer rebooting?

As the title please. I just want Windows Update to locate and install updates as usual, but hold off the reboot until I'm back at my PC. I leave an AI server running on 127.0.0.1 (my own PC) overnight and my Synology NAS does a daily backup at 08:00. If the PC restarts without my knowledge, then the AI server is stopped and the NAS can't backup my PC on that day. I also lose some of my open Windows, although to be fair, Windows does re-open any unsaved Notepad and Notepad++ Windows with their unsaved data still in them. Windows 11.

I searched on here and on Google and attempted 2 solutions:

1. Go to Settings > Windoiws Upate > Advanced > Notify me when a restart is needed (toggle this on)

2. Go to regedit > HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows. In Windows create a key called WindowsUpdate. In WindowsUpdate, create a key called AU. In AU, create a 32-bit DWORD called NoAutoRebootWithLoggedOnUsers and set the value to 1.

Both solutions are still in place now after a few months (just to be absolutely certain) but neither of them had worked.

Thanks @Rroff - I'll have a look at that. I don't want to stop it completely. Just have it so a notification by the clock / systray says that a reboot is required upon returning to the PC. So then I can close my programs/server correctly then reboot.

In fact, my work's PC is set up like this, probably by Group Policy / IT admin, which allows me to close down all of my work then click on reboot on the systray prompt.
