How to Specify Pixel-Specific Depths of Views in xrOS?

With the advent of the third dimension, I wanted to know wether if it's currently possible to display the flat swiftUI Views with some thickness in xrOS? While the .frame(depth: CGFloat?) does the job for Views in general, I am eager for a more granular level of control at the pixel-specific level.

I was hoping that there are lower level APIs to achieve this & I've looked into the fairly new layerEffect shader API, yet it seems it's incapable of setting the depths of pixels...
