function add_readonly_and_disabled_to_text_field($field) {
    acf_render_field_setting( $field, array(
      'label'      => __('Read Only?','acf'),
      'instructions'  => '',
      'type'      => 'radio',
      'name'      => 'readonly',
      'choices'    => array(
        1        => __("Yes",'acf'),
        0        => __("No",'acf'),
      ),
      'value' => 0,
      'layout'  =>  'horizontal',
    ));
    acf_render_field_setting( $field, array(
      'label'      => __('Disabled?','acf'),
      'instructions'  => '',
      'type'      => 'radio',
      'name'      => 'disabled',
      'choices'    => array(
        1        => __("Yes",'acf'),
        0        => __("No",'acf'),
      ),
      'value' => 0,  
      'layout'  =>  'horizontal',
    ));
  }

If you would like to use ACF's standard style that it uses for choices when creating fields. i.e. true/false field:

add_action('acf/render_field_settings/type=text', 'add_readonly_and_disabled_to_text_field');
function add_readonly_and_disabled_to_text_field($field) 
{
	acf_render_field_setting( $field, array(
	  'label' => __('Read Only?'),
	  'instructions' => '',
	  'name' => 'readonly',
	  'type' => 'true_false',
	  'ui' => 1,
	), true);
	
}

The parameter 'value' => 0 must be removed else it doesn't save current state.
