16 Bit Depth Buffer

Hi there !
The documentation states that it would be beneficial to use a 16bit depth buffer and no stencil, but doesnt tell us how to achieve this.
Does anybody know how ?

I am using Unity 2019.4 with URP 7.4 & Oculus Quest 1
I tried brute forcing the depth buffer to 16 bit by editing in UniversalRenderPipelineCore.cs function:
 static RenderTextureDescriptor CreateRenderTextureDescriptor(Camera camera, float renderScale,
            bool isStereoEnabled, bool isHdrEnabled, int msaaSamples, bool needsAlpha)

Just add this line before return : desc.depthBufferBits = 16; // Override to 16 bit depth

And it clearly works in Editor as i get a lot more z-fighting with big camera clipping planes, but when i use ovrgpuprofiler or renderdoc it still shows me DepthBuffer with 24bit and 8bit Stencil.

I really hope someone from Oculus chimes can help with this!

Best regards,
Tim

    I guess it's here:
    Project Settings > XR Plug-in Management > OpenXR > Tab: Android > Depth Submission Mode: Depth 16-bit

      This has (incredibly) been removed, so we all now are facing the stupid Z buffer problem again.
