RealityView clip volume

Is there any way to specify a clip volume or clipping planes on either a RealityView or the underlying RealityKit entity on visionOS? This was easy on SceneKit with shader modifiers, or in OpenGL, or WebGL, or with RealityKit on iOS or macOS with CustomMaterial surface shader, but CustomMaterial is not supported on visionOS.
