In Drupal 7 we were able to use `field_attach_update($entity_type, $entity)` to update fields without having the need to update the whole node. `$node->save()` is very heavy and calls many hooks in between.

With the coming of Drupal 8, `field_attach_update` was deprecated. Is there an alternative to it, and what is it if yes? 

In my case I'm updating two image fields programatically and don't want to call `$node->save` in order to not trigger all the other hooks.
