Question AR Foundation: Disabling native ToF depth sensor

Hi,

I have a Samsung S20 and it has a time-of-flight depth camera.
When ARCore sees that this depth camera is available it will generate its depth map from it.

But then the depth map is sluggish/not in sync with the RGB frame, because the depth sensor works only at 5 fps.

In ARCore sdk itself there is a flag that I can disable the use of hardware depth sensors and my problem is solved.
But I cannot seem to find this option in ARFoundation in order to disable native depth sensor.

Question 1: Where is the option in order to disable the native depth sensor (like in ARCore SDK)?

Question 2: I also cannot seem to find the lens intrinsics of the depth image in AR foundation...

 

Ok, it seems with "ARCore Extensions" I can disable the ToF sensor.
