Vulkan and DirectX are the favored graphics rendering technologies for VR.
Godot supports Vulkan rendering via OpenXR.
To get a vibe for Apple’s general posture in this regard it is worth noting that Vulkan rendering through OpenXR on macOS is technically possible via MoltenVK, but macOS does not have an official OpenXR runtime. You’d need to use third-party workarounds or wait for broader support.
