There isn't ever going to be official support for it, that's for sure. As for unofficial support, it's going to take some nerds to put that together. It could be you! Go buy one and start working on it. Let us know how it goes. I'm sure you can get a lot of enthusiastic people to help you. Personally, I think a better and easier option is to just get an entire other computer with the GPU(s) in it. This can either be a physical machine you have, or some GPU cloud instance. Then in situations where the Mac graphics capabilities aren't up to snuff, you can use something like remote desktop or streaming to offload that work to the other machine. e.g.: Setup a small headless PC on your network that has a powerful GPU and Steam installed. Then run Steam Link on your Mac to play games that don't run natively on MacOS.
