Disable back button for module react-navigation, use hook useFocusEffect

const hardwareBackPressCustom = useCallback(() => {
        return true;
    }, []);

useFocusEffect(() => {
    BackHandler.addEventListener('hardwareBackPress', hardwareBackPressCustom)
    return () => {
      BackHandler.removeEventListener('hardwareBackPress', hardwareBackPressCustom)
    };
  }, []);
