Windows 11 installation wizard should give us a choice of "isolated mode" or "standard mode"

As a developer, I install Windows 11 for testing purposes. I may install "bad" software there. I don't want Windows to see my documents on Mac. I know I can change the configuration to "isolated mode" after installation, but during installation Windows may have already accessed my file on Mac and made some logs. This is my concern. So I think it's better to ask the user if he would like to isolate Windows before installation.
