Thank you for that screenshot, provided the PC's have a 6th gen processor (1) and Windows 10 is installed in UEFI Mode (2), then you can upgrade them to Windows 11, but Microsoft indicate they will not be responsible for any problems that may ensue, many people have upgraded to Windows 11 on unsupported 6th gen processors and Windows 11 runs smoothly with no problems and they have received all updates, the only problem you will experience is when version 24H2 is released, you will not be able to install that update when they block the registry tweak.
Microsoft provide the required registry tweak on this link and you would need 40GB of free space on the C drive and use the Windows 11 ISO to perform the upgrade.
