Can I reimage the OptiPlex 3000 thin client from Windows LoT to ThinOS

Hey there

We bought some subject mentioned thin client a while ago with Windows OS, we are going to buy more with ThinOS for easy management, and I am wondering if we can reimage those windows OS thin Client into ThinOS?

If yes, kindly point me the document or link, where to download the thinOS and how to do it.
