Eloquent model mass update

Question

Please correct me if I am wrong, but I think there is no such thing as mass update in an Eloquent model.

Is there a way to make a mass update on the DB table without

Use database transactions to update multiple entities in a bulk. Transaction will be committed when your update function finished, or rolled back if exception occurred somewhere in between.

https://laravel.com/docs/5.4/database#database-transactions

For example, this is how I regenerate materialized path slugs (https://communities.bmc.com/docs/DOC-9902) for articles in a single bulk update:

public function regenerateDescendantsSlugs(Model $parent, $old_parent_slug)
    {
        $children = $parent->where('full_slug', 'like', "%/$old_parent_slug/%")->get();

        \DB::transaction(function () use ($children, $parent, $old_parent_slug) {
            /** @var Model $child */
            foreach ($children as $child) {
                $new_full_slug  = $this->regenerateSlug($parent, $child);
                $new_full_title = $this->regenerateTitle($parent, $child);

                \DB::table($parent->getTable())
                    ->where('full_slug', '=', $child->full_slug)
                    ->update([
                        'full_slug' => $new_full_slug,
                        'full_title' => $new_full_title,
                    ]);
            }
        });
    }
