Very sorry i have been slammed at work. 

Yes, i just spun up a Hyper-V Windows 10 VM on static IP with a shared folder for just 2022 files. Then mapped it to their workstations and installed QB Database Server 2022 on the Windows 10 VM and let it run it on the host. It runs it just like a server and have not had issues yet. Only thing is to try and limit the upgrade to 2022 until all of their clients or books can move over. Once they can, you can move all the files back to their main server, remove all old QB Database installs and install 2022 or 2023 by that time.
