You should be able to try to get on Windows Insiders Dev channel to get official. Some people had no issues taking a Windows Update supplied update to WIn11, but some (including me) did. But at this point even getting on the Dev channel might be a chore.
You can also use UUPDUMP to grab the latest yourself and perform an in-place upgrade, and see if it works.
To do so, you'll need to see this tutorial:
UUP Dump - Download Windows Insider ISO
And once you have the .ISO created, you need to follow this tutorial:
Upgrade to Windows 11
Note: Make a full backup of your system before proceeding - so if it breaks, you can at least restore to where you are now.
