When translating a node, can I avoid copying the default value from the original language

Question

Just a little background: I've got a set of paragraphs fields that I need to be able to translate, and given the limitations on translation with paragraphs, I've come up with the idea, that it may just be best to create a new node of a new content type (for holding the paragraphs fields) for each language of the main node. I would then use Inline Entity Form to bring those fields into my main node.

The problem I run into is that translation copies the value from the original language when I create a translation. Most of the time this is desirable, but in this case, it means that all languages get the same referenced node, when I specifically want them all to have their own new node.

Is there any way to suppress the value copy functionality for a specific field when translating?

Unset the field values in a hook_ENTITY_TYPE_translation_create:

use Drupal\node\NodeInterface;

/**
 * Implements hook_ENTITY_TYPE_translation_create().
 */
function mymodule_node_translation_create(Nodeinterface $translation) {
  if ($translation->getType() == 'product') {
    unset($translation->body);
  }
}
