Build BP3A.250905.014, replaces "Allow home screen rotation" (which used accelerometer) with "Landscape mode" (permanent on/off); how to restore this?

Before *Android OS 16*'s last update (to build # BP3A.250905.014), Home settings had Allow home screen rotation (if enabled, this uses the accelerometer so that home is vertical if the phone is vertical, or horizontal if the phone is horizontal. - This was the sole option that allowed you to hide the *Google* search bar; if you disabled the *Google* app and enabled this option, then when your phone is horizontal, the *Google* search bar does not show.  But BP3A.250905.014 replaces this option with Landscape mode (which is a permanent on/off switch). - It is now not possible to hide the *Google* search bar unless you replace the stock launcher (such as with *Nova Launcher*, which is not recommended). With the new Landscape mode, even with the *Google* app disabled and the phone horizontal, the *Google* search bar shows.  How to restore the old home view? - Do you have to undo the update (roll back to the old version) to restore this ("Alt + Tab" switches)? Have the stock *Android OS* (not [**AOSP**](https://source.android.com/) , which includes sudo); is it possible to go back to the old version on devices without sudo? - Do you have to purchase a new phone (and remember to disable all processes related to "updates" / "provisioning" (and *Google* still asks, refuse those))? - If you can not refuse those: use without the **SIM** card (so *Google* can not force those), or [switch to a new **OS** (such as *Ubuntu Phone*) which allows you to use your phone](https://android.stackexchange.com/questions/57674/ubuntu-for-android) ?
