Hi,
Thank you for posting in Microsoft Q&A forum.
MDT can support for the newer operating systems, for example Windows server 2019 and Windows 10. However, the older systems, for example Windows XP and Windows 7, are long out of support, and because there is no longer support there also is no patching or testing for XP and Windows7 scenarios. So, while it may work today there's really no guarantee for tomorrow.
We can follow below guides to setup MDT environment to support the newer operating systems:
