External Keyboard not working on main menu on Android Device (Android TV Box) about retroarch HOT 3 OPEN

I've read this on Reddit, but I can undertand how to change this configuration in retroarch.cfg

ANDROID: In Android builds, add input_android_physical_keyboard configuration option and its corresponding menu entry to force a device to act as a physical keyboard. When running on Android, RetroArch considers most devices that emit dpad events as gamepads, even if they also emit other keyboard events; this is usually the right thing to do, but it has the side effect of not letting some actual keyboards (e.g.: Logitech K480) act as such inside RetroArch. This configuration option allows users to manually select a specific input device to act as a physical keyboard instead of a gamepad, which is handy when emulating computers as opposed to consoles.

input_android_physical_keyboard = "Logitech Unifying Device. Wireless PID:4024"

Is something like this?

The physical keyboard option should be visible in Settings / Input, probably at the bottom, if you can control the menu temporarily with some other device.

The main problem is that my PS2 Controller presents the same problem.
Maybe another one?
