Developer Options on Android are intended for advanced users. If you no longer use them, you can easily disable these settings by following the next steps: 

1. Open the Settings app on your phone.
2. Scroll down and tap on System (or on some devices, About phone).
3. Tap on Developer options.
   👉 Don’t see this option? Developer options are already disabled.
4. Turn off the switch at the top of the screen (next to Developer options).
   The developer options will now be disabled, and the menu will usually disappear automatically from the settings menu.

Then go back to the main settings menu to check if the option has indeed disappeared.
