On my G7 Play with LineageOS, I was able to "disable" the notch -- that is, draw a black bar around it, and have a proper rectangular display with a full-width status bar right below it.

Works great, especially considering the display is not quite small enough for me in the first place.

You can do that with the stock Android too, once you've enabled the developer options in settings. The setting needed is "Display cutout" --> "Hide".
