Question about the download adk files verison not found in microsoft website

I was trying to find configmgr 1902 version since my windows 10 pro version has 1802 and the windows server 2019 for SASCCM01 version is 1809 and SADC01 version is also 1809. So where to download the adk files for configmgr 1902 since I don’t see it since microsoft have most likely removed that version from the official website. I’ve used it in virtualbox. Or would I need to download new version of windows 10 pro or new version of windows server 2019.

Yes I would download Windows server 2019 and Windows 10 pro.
Thanks,
Robert
