It works fine on Intel Macs with supported hardware, but after a bit no new updates came for newer GPUs and because the corporate relation between Apple and Nvidia got shot to the around the 8600/8800 GPU series debacle, the only eGPUs that work on macOS on Intel were AMD gpus. You could run Windows and use GPUs there, but on ARM that's a different story, there don't seem to be any Windows or macOS drivers at all, except for Linux. So would it work hardware-wise? Yep. But no official software is being made to do it because none of the parties that could are incentivised to do so.
