Change Unity 3d Audio Spatializer Plugin

I'm looking for a way to change the audio spatializer plugin using code. For different platforms, we have different spatializers. I can make this change either in editor runtime, or application runtime..but for now I can't find any way to do it.

I want to be able to say something like

UnityAudioSettings.spatializer = "None"; or UnityAudioSettings.spatializer = "SomePlugin";
