I have a View, it is ajax View. There are exposed filters (with checkboxes). When I select a checkbox \Drupal::routeMatch()->getRouteName() shows general route name: views.ajax

I need to change view mode in the view:

function entity_product_admin_entity_view_mode_alter(&$view_mode, \Drupal\Core\Entity\EntityInterface $entity) {
  if ($entity->getEntityTypeId() == 'node' && $entity->bundle() == 'product' && \Drupal::routeMatch()->getRouteName() == 'views.ajax') {
    $view_mode = 'product_card_full_width';
  }
}

But in case Drupal::routeMatch()->getRouteName() == 'views.ajax' $view_mode will change on all ajax requests, but I need it to change only on a specific field of the form.

This hook seems to be not very useful in a Views context. You don't get much information, not even the view name. In an Ajax request Views removes any POST data from the request before executing the View.

You would need to save the view name (or any other POST data) at the start of the request in an event subscriber:

  public function onKernelRequest(RequestEvent $event) {
    $request = $event->getRequest();
    $view_name = $request->request->get('view_name');
    $request->attributes->set('view_name', $view_name);
  }

Use drush gen service:event-subscriber to generate the scaffolding.

Then the hook can get the view name:

$request = \Drupal::request();
$view_name = $request->attributes->get('view_name');
