Remove a PreferenceScreen from a List

To access this PreferenceScreen (Configuration)

First I have to access a list

and select the option and I just laza the options menu (Settings), I need that from the beginning the options menu is launched without having to enter the list, how can I do it?

This is the code:

public class SettingsActivity extends AppCompatPreferenceActivity {
private static Preference.OnPreferenceChangeListener
        sBindPreferenceSummaryToValueListener = new Preference.OnPreferenceChangeListener() {
    @Override
    public boolean onPreferenceChange(Preference preference, Object value) {
        String stringValue = value.toString();

        if (preference instanceof ListPreference) {
            ListPreference listPreference = (ListPreference) preference;
            int index = listPreference.findIndexOfValue( stringValue );
            preference.setSummary(index >= 0 ? listPreference.getEntries()[index] : null );
        }else {
            preference.setSummary( stringValue );
        }
        return true;
    }
};

private static void bindPreferenceSummaryToValue(Preference preference) {

    preference.setOnPreferenceChangeListener( sBindPreferenceSummaryToValueListener );
    sBindPreferenceSummaryToValueListener.onPreferenceChange( preference,PreferenceManager
                    .getDefaultSharedPreferences( preference.getContext() )
                    .getString( preference.getKey(), "" ) );
}

@Override
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public void onBuildHeaders(List<Header> target) {
    loadHeadersFromResource( R.xml.pref_headers, target );
}

protected boolean isValidFragment(String fragmentName) {
    return PreferenceFragment.class.getName().equals( fragmentName ) || ConfigCOM.class.getName().equals( fragmentName );
}

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public static class ConfigCOM extends PreferenceFragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate( savedInstanceState );
        addPreferencesFromResource( R.xml.pref_setup_com );
        setHasOptionsMenu( true );

        bindPreferenceSummaryToValue( findPreference( "config_baud_rate" ) );
        bindPreferenceSummaryToValue( findPreference( "config_data_bit" ) );
        bindPreferenceSummaryToValue( findPreference( "config_bit_stop" ) );
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if (id == android.R.id.home) {
            startActivity( new Intent( getActivity(), SettingsActivity.class ) );
            return true;
        }
        return super.onOptionsItemSelected( item );
    }
}

}
