Unfortunately, until RavenDB itself starts supporting ARM on Windows, you are correct that no native Windows version of our Platform will work for you.
However, if your goal is to have some sort of version of our Platform running locally, we do have Linux-based containers that will work for you.
Take a look at PlatformContainerExamples/docker-compose at main · Particular/PlatformContainerExamples · GitHub for an example Docker Compose file that you should be able to use and customize.
