Lenova 11e - Chrome OS updates at EOL - compatible OS?

Support Device Recommendation
1

Our elementary school can no longer run accelerated reader quizzes and I-Excel on the 11e chromebooks. If I follow Mr.Chromebox instructions for FullRom firmware - what OS would be best for the 11E hardware limitations - ChromeFlex or Windows(version?) ? Or is there a trick to force the chrome OS to continue updating after EOL?
Thanks!

You can install a Linux distro on your Chromebook. If your Chromebook is too slow to run DEs like GNOME or KDE then you can look up lightweight Linux distros / DEs.

You may not have fully working stuff if you install ChromeOS Flex.

Flex will have issues on that.
