ADB immersive mode and wm overscan commands no longer work on Android 11

I upgraded to Android 11 without knowing that it broke compatibility with existing immersive mode and window manger overscan adb commands. Are there new alternatives to these commands in adb now? I was specifically using:

shell wm overscan 0,0,0,-136 (reset: 0,0,0,0)

shell settings put global policy_control immersive.status=*

For reference I'm running GrapheneOS on build number RP1A.200720.009.2020.09.25.00 on a Pixel 3 with Android 11 on Kernel version 4.9.223.
