Integration of (cloned and adapted) noderelationships_backref view with per-role Page displays (sharing identical path) in View

I've found where Node Relationships is overriding the view Page display paths.
From noderelationships.inc:

/**
 * Apply custom configuration to the given back reference view.
 */
function noderelationships_customize_backref_view(&$view, $display_id, &$view_args, $reset_current_display = TRUE) {

// ...

  // Customization related to the page display.
  if ($view->display_handler->display->display_plugin == 'page') {

// ...

  // Reset the current page display so that the changes take effect.
  // This is necessary for AJAX requests and page displays managed by
  // the views menu callback.
  if ($reset_current_display && isset($view->current_display)) {
    unset($view->current_display);
  }

  // Activate the specified display.
  $view->set_display($display_id);

  // Allow external modules alter the view.
  drupal_alter('noderelationships_view', $view_overrides, $view, $display_id, $view_args);

  // Apply dynamic customization to the view display.
  foreach ($view_overrides as $option => $definition) {
    $view->display_handler->override_option($option, $definition);
  }

// ...
}

As far as I can tell, Node Relationships backref facility is always going to call the default view display anyway, not an access-specific Page (no matter what path).
From noderelationships.pages.inc:

function noderelationships_backref_render_view($back_reference_view, $context, $render_view_title = TRUE) {
  static $pager_element = 0;

  $referred_node = &$context['referred_node'];
  $referred_type = &$context['referred_type'];
  $referrer_type = &$context['referrer_type'];
  $field_name = $context['field_name'];

// ...

  // Prepare the name of the view and display.
  if (empty($back_reference_view)) {
    $view_name = NODERELATIONSHIPS_BACKREF_VIEW_NAME;
    $display_id = 'default';
  }
  else {
    list($view_name, $display_id) = explode(':', $back_reference_view);
  }

// ...

I would like to be able to force the node relationships backref views to call on a specific Page display path (which is shared by multiple Page displays with different access level, and showing different fields per role).

[Note that this is not even the same as selecting a specific a Page display option, Views will switch between Page displays according to access role, for a given shared path, not by display id, as described by merlinofchaos: http://drupal.org/node/755956#comment-2791922 ]

@markus_petrux Thanks for tip, will try out and report back result here.
