How to translate the layout builder blocks of a node programmatically?

I am translating the nodes programmatically. Everything works fine except the layout builder blocks.

When I try to translate it, it also changes on the source node.

I have created a node in language en. Now I am translating it to nl. Here is my code.

if ($node->hasTranslation($language)) {
  $translated_entity =  $node->getTranslation($language);
}
else {
  $translated_entity =  $entity->addTranslation($language);
}

$translated_layout = $node->get('layout_builder__layout')->getValue();

foreach ($translated_layout as $section) {
  /** @var \Drupal\layout_builder\Section $section */
  $section = reset($section);

  foreach ($section->getComponents() as $component) {
    $configuration = $component->get('configuration');

    $component->setConfiguration($translated_configurations);
  }
}

$translated_entity->set('layout_builder__layout', $translated_layout);
$translated_entity->save();
$node->save();

Is there any way to retain the original blocks as it is on the source node and the save function only added the changes to the translated node?
