ARFoundation Environment Occlusion glitches - Is it possible to do smoother occlusion?

Hello, I would like to ask if it is possible to adjust the smoother occlusion when using the AR Occlusion manager. If I place a carpet object on the floor and use occlusion, sometimes certain glitches occur, as can be seen in the picture (or video : https://drive.google.com/file/d/1dm1aSullslT5yDVtN3_JUGH2k8kAsN-m/view?usp=sharing )
I´m using ARFoundation and ARCore version -4.1.7, but I also tried a version of 4.2.1 and new 5.0.0-pre.5 version but I don´t have any visual changes.
I will be very grateful for any advice that will help me solve this problem.
