Its not good solution to temporarily modify entity objects only for change API response format.

Better solution is using DTO/Transformer classes. Good example of transformers implementation is https://fractal.thephpleague.com/transformers/

In this way you can split presentation and model.

Using any packages is optional, you can write simple transformer classes like this:

// app/Transformers/ArticleTransformer.php
final class ArticleTransformer
{
    public static function transform(Article $article): array
    {
        return [
            'id' => encrypt($article->id),
            // any fields
        ];

        /*
           // or if you need change only one property
           return array_replace(
              $article->toArray(), // or $article->jsonSerialize()
              [
                  'id' => encrypt($article->id),
              ],
           ); 
        */
    }

    public static function transformCollection(Collection $articles): Collection
    {
        return $collection->map(fn (Article $article): array => self::transform($article));
    }
}

Then use this transformer:

return [
  'latest_data' => ArticleTransformer::transformCollection($latestArticles),
];

Not very good, but should work:

Override jsonSerialize/toArray method of model, in returning modify your id.
