Pro licences here. Can't say as I've found an option like that. Is it relatively new? I've not dug around terably recently. Everything else people have suggested either hasn't worked or did for a while then changed after an update.

Group Policy for Windows Update "configure automatic updates" can be set to "notify for download".

I'm pretty sure I've tried that and it reset itself a time later.

Looking again now, there seems to be no such option. I can defer updates for a fixed number of days (with separate settings for quality updates and feature updates), which might be useful if the defer is cancelled by a manual "check and install updates" rather than having to reset the setting to get them to install at a convenient time rather than waiting for them to go in at Windows' will at the end of the defer period.
