Windows 11 Upgrade to Pro

Good evening, I'm Gerry and I just purchased and received a Dell XPS 9710 Laptop yesterday.  I've been setting it up and, so far, no issues.  It came with Windows 11 Home and that's fine but I would like to upgrade to Win 11 Pro as I do need the domain options but there's no option for that either on the original order page or searching the Dell website.  Everything I run into is about upgrading from Win 10 to Win 11.

So, what are my options for this upgrade? I tried emailing Dell tech support about this but got no response.  Best case would be to purchase a Windows 11 code from Dell to authorize the upgrade from Windows 11 Home to Windows 11 Professional.  Thank you in advance for the help.

Thank you,

Gerry
