How to change date format of exposed filter input value?

By default view exposed filter ,filtering the data in such way. http://mydomain.docksal.site/events?combine=&field_event_categories_target_id=All&field_start_date_time_value=&field_start_date_and_time_value=2023-01-07. When we inputs the date field in such format 2023-01-07

But customer wants to filter the date in dd/mm/yy When we pass the date in exposed filter in such format 07/01/2023 ,then no result found in views.

I want to filter the data in dd/mm/yy format ,below is my code.

   function goldfarb_custom_form_alter(&$form, \Drupal\Core\Form\FormStateInterface $form_state, $form_id) {
  $view_names = array('events');
  $view = $form_state->getStorage('view');
  if ($form_id == 'views_exposed_form' && in_array($view['view']->id(), $view_names)) {
    $form['#validate'][] = 'my_exposed_validate';
  }
}
function my_exposed_validate(&$form, \Drupal\Core\Form\FormStateInterface $form_state) {
  //die();
  date("Y-m-d",strtotime($form_state->getValues('field_start_date_and_time')["field_start_date_and_time_value"]));
  dump($form_state->getValues('field_start_date_and_time')["field_start_date_and_time_value"]);
}
