I doubt it will ever be "officially" supported given the limited 3D support and YYG always saying they have no intention of focusing on 3D. Other engines are also much better suited if you are really interested in developing for VR... Will Gamemaker Studio receive official VR support ?
There have been some attempts at VR extensions though, most recently GMCardboard which works with Google cardboard and other extensions such as GMOculus and support for HTC Vive though both are pretty old now and it seems they are no longer being developed/supported.
Maybe they could be used as a starting point for your own project though if VR in GM is something you really wanted to persue rather than use Unity/Unreal which both make VR trivial in comparison to what you'd have to do in GM to get even basic support working.
