There seems to be an alternate build of Kicad that offers DM support for windows users. The Huaqui build.

I see they also have the latest 9.0.4 fork. I had it installed briefly (It set off some Avast AV warnings when I installed it) and it comes with plugins that I didn’t particularly want so I uninstalled it as I’m also migrating to Linux Mint so if/when I really want a more proper DM, I just boot into Linux vs Windows.
