Plane finding and light estimation can not be disabled in instant preview mode

[few2net]

I used instant preview to test my project (with ARcore 1.4 and pixel phone2 ).
What I was doing is to give my application will detect horizontal plane only.
To do that, I changed a setting in session config.
I tried to build and run on my phone and It was work, but in instant preview mode It was not.
Btw, I found that not only plane finding mode but also light estimation
can't be changed in instant preview mode.

This is not an issue SDK already warns you about it when you attempt to disable surface detection in instant preview
