I don’t know when the last time you tried to install Windows was, but when I installed Windows 11 Pro yesterday, there was no obvious option to install without an internet connection and a Microsoft account. To make that option appear, I had to hit shift+f10 at the country selection screen to open a command prompt and run the script located at “oobe\bypassrno.cmd” to have the option “I don’t have an internet connection” to pop up and allow me to bypass needing a Microsoft account.
