Hi,
Thanks for posting in Microsoft Q&A forum.
Per my experience, devices are named using settings specified in Domain Join configuration for Hybrid Azure AD joined type of Autopilot deployment profiles. It's a little strange to show the page "Let's name your PC" in OOBE. With Q&A limitation, it is suggested to create an online support ticket to handle this issue more effectively. It is free. Here is the online support link and hope it helpful.

Thanks for your time.
Best regards,
Simon
