According to this reddit post, you can upgrade from Windows 10 22h2 Pro to Server 2022 Standard. According to a reply by Skye on her video, "You can't upgrade to or from Starter editions, but you can upgrade to lower editions by changing a few things in the registry. People upgraded Server 2008 R1 to 7 that way for example." According to an answer on this Microsoft Learn thread, you can also upgrade Windows GAC to LTSC.

Edit: Massgrave has a guide on upgrading GAC to LTSC
