hook_field_views_data_alter(array &$data, \Drupal\field\FieldStorageConfigInterface $field_storage)
Alter the Views data for a single Field API field.
This is called on all modules even if there is no hook_field_views_data() implementation for the field, and therefore may be used to alter the default data that views_field_default_views_data() supplies for the field storage.
Parameters
array $data: The views data for the field storage. This has the same format as the return value of hook_views_data(). @param \Drupal\field\FieldStorageConfigInterface $field_storage The field storage config entity.
