if you're not going to let me do this microsoft then let me turn off auto restart all together.

The real solution is to set it so it starts just before you are supposed to wake up, and ends 6 hours before that. That gives you the active hours as intended, and it won't reboot the system in the middle of work ever again.
The whole point of this option existing is to keep the system from auto install/reboot in the middle of work. You're telling the machine when it's not okay to do this... so you're the one in control.
I wouldn't say I'm in control per se when I don't have the option to just do the update whenever I feel like it. I'm in control the same way a prisoner is in control of whether or not they eat that day by just not eating. Like, put it behind a giant bold unmissable piece of text that says "IF YOU DO THIS YOU ARE PUTTING YOUR MACHINE AT RISK AND HACKERS WILL IMMEDIATELY STEAL ALL YOUR MONEY" but don't make it so it's impossible for me to do without some workaround.
