You could run it in a KVM or VirtualBox instance in seamless mode.
That’s probably your simplest solution. W10 can run without quite well lightweight on a virtual instance. In fact it was designed to be instancable easier than pre W10 releases (activation was a hurdle for those releases on VM’s).
You can find ISO images on the Microsoft site here Download Windows 10 Disc Image (ISO File) (Microsoft official site).
What I would like to see is a web version of EveMon, one we can self host. I opened a topic on that here Web version of Evemon / EVE Portal mobile type functionality for characters
People have also been wanting builds for Mono for EveMon or a native version with QT perhaps. The problem is CCP forces a “devkey”, and not just the user ESI token. I am certinally not going to release desktop apps in the wild with MY devkey PKCE challenge on it. My devkey is for MY use, nobody else.
