Hey, how you doing?
Thank you for contacting us and welcome to the Microsoft Community.
My name is Vitor. I'm an Independent Advisor and I'll be glad to help you today.
During Setup ignore the option to "connect to a network' and click "I do not have internet" and confirm the creation of a Local account. When the installation is complete you can sign in to a Microsoft account.
If there were more questions or need more information, do not hesitate to ask.
Thanks
Vitor S.
