This is just for Home edition, yeah? Pretty sure Professional still allows you to create offline accounts without a Microsoft account before joining a domain.
Last time I tried it let me create a local account, then about a week later I got called because Windows threw a full-screen blocker on boot saying a Microsoft account was required to continue with "I'll do it later" being greyed out. Oddly enough, ALT+F4 worked to close it and continue.
I tried not too long ago and had issues. I don't know if they hid it somewhere else, or removed it, but I ended up installing using a different method.
I do know they made it a pain in the ass to find the last time I built a computer, but I did eventually find it... though things may have changed in recent weeks.
You do it essentially while joining the domain. If you hit the "work" option instead of "home" it immediately goes to a "sign into your domain" screen.
