This is to bypass Microsoft ID Requirement not actually the issue for people who don't have internet connection.
The Open cmd with Shift + F10 and type OOBE\BYPASSNRO. was mandatory for me when Windows didn't recognize my WiFi card. You'd think they'd make it easier for those people who just don't want to install Dell version of Windows 11. I truely hate McAfee!
No, you can bypass both.
I can install without internet connection using the oobe\bypassnro with any windows 11 build, public or insider.
I just did it a few days ago without any problem.
