I haver the following factory:

namespace Database\Factories
use App\Models\Policy;
use App\Models\A;
use Illuminate\Database\Eloquent\Factories\Factory;

/**
 * @extends \Illuminate\Database\Eloquent\Factories\Factory<\App\Models\A>
 */
class VersionFactory extends Factory
{
    /**
     * Define the model's default state.
     *
     * @return array<string, mixed>
     */
    public function definition(): array
    {
        $this->afterMaking(function (Version $model){
           if(!empty($model->policy_id)){
               return;
           }

           $randomB = B::inRandomOrder()->first();
