I checked and I also don't see it. Not sure why. I checked the camera app's code, and it looks like the app checks if ZSL is supported, then only displays the option if it is.
My guess is that the software is reporting it's not supported for some reason. Like the Android docs say:
isZslSupported
can be used to query the device capability to support this mode or not. However, this mode also depends on use cases configuration and flash mode settings. If VideoCapture is bound or flash mode is not OFF or OEM Extension is ON, this mode will be disabled automatically.
Hopefully one of the developers comes along and can give a definitive answer.
