You would probably need to do a GPU passthrough wich depending on what kind of graphics card you have would be near impossible. The easiest thing to do would just to get a large USB or portable hard drive, install Linux on it and use that to do your RPG maker. You can get a 128GB USB for $20 and Linux is free. If you want to go this route I recommend Manjaro or Ubuntu, both of them are pretty user-friendly and for the most part ready for steam games at least with Manjaro, I've heard ubuntu has been going downhill lately as far as working with games and not to mention you have the amazon integration as well.
Linux Distro TL,DR: I recommend Manjaro but you have many options which are all free by nature.
