I actually don't know
Looks like you are missing the basics. 😎
The procedure described on page 1, works perfectly if you are not connected to the network via Ethernet. I just tried it with the installation media 22621.1702 downloaded today from Microsoft.
In the case you are connected it will just proceed to a normal online installation and you will never have the chance to enter Shift + F10 and the command oobe\bypassnro and reboot, in that situation you will never see the message "I don't have internet" option.
It will just ask you to sign in.
If you get to that point, there is still a way to avoid the MS account sign in and create a Local Windows account instead.
That is a different hack procedure described in a different thread. 😎😂😉
Good luck! 😉🤷♂️
