AR Quick Look additional controls?

I've recently added some USDZ files to a web page, and I can download and display them fine via AR Quick Look on an iPhone or iPad.

I've noticed full occlusion is active in the AR view.

Over time, the device appears to heat up and the frame rate drops.

Are there any properties I can set in the <a rel="ar" ...> HTML tag to control things like occlusion or autofocus (i.e., turn them off)?
