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.ymlProduct:      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:
