How to set up a cluster including MacOS and Linux nodes

In the official document Ray Cluster Overview, there is a note below the topic Where can I deploy Ray clusters, it said that

Multi-node Ray clusters are only supported on Linux. At your own risk, you may deploy Windows and OSX clusters by setting the environment variable RAY_ENABLE_WINDOWS_OR_OSX_CLUSTER=1 during deployment.

However, when I throughout the api reference, I didn’t find any introduction to this setting, does anyone know how to set it up?
