Set easyadmin_autocomplete Select Null by default. Symfony

I would like to know if there is any way to put null value by default in the easyadmin_autocomplete select.

The first item in the list is selected and filled with data from database but i need a null value by default and setted automaticly. The goal is a first result point to an empty one (Choose one...).

Do you know how to do it?

Can you think of any way combining the options defined below?

#easy_admin.yml
Product:
      class: App\Entity\Product
      controller: App\Controller\ProductController
      new:
        fields:
          - { property: 'category', label: 'Category', type: 'easyadmin_autocomplete', type_options: { class: 'App\Entity\Category' } }
 }

In this example, one select has a placeholder with the text 'Any' (Ninguno). I need to know why is handling them different. These are the options defined for the attr fields -> type_options of the yml:

1. action
2. allow_extra_fields
3. allow_file_upload
4. attr
5. auto_initialize
6. block_name
7. by_reference
8. class
9. compound
10. constraints
11. csrf_field_name
12. csrf_message
13. csrf_protection
14. csrf_token_id
15. csrf_token_manager
16. data
17. data_class
18. disabled
19. empty_data
20. error_bubbling
21. error_mapping
22. extra_fields_message
23. help
24. help_attr
25. inherit_data
26. invalid_message
27. invalid_message_parameters
28. label
29. label_attr
30. label_format
31. mapped
32. method
33. multiple
34. post_max_size_message
35. property_path
36. required
37. translation_domain
38. trim
39. upload_max_size_message
40. validation_groups

If setting your default value would be a solution for you (like zero), service listener might be an answer:

// You need to add this listener yourself:
class ProductServiceListener
{
    ...

    // you can manipulate entity in this level as you wish:
    public function preUpdate(LifeCycleEventArgs $args)
    {

       // You will focus to Product entity, so block others:
       if (!(get_class($entity) == 'App\Entity\Product')) {
           return;
        }

        // Set whatever default value you want if it's null:
        if($entity->getCategory() == null) {
           $entity->setCategory(0); // Zero, as an example.
        }
