You can use distinct rule of laravel array validation.

$validator = Validator::make(
          ['products' => 
            ['product_id' => 1, 'quantity' => 5],
            ['product_id' => 1, 'quantity' => 99],
            ['product_id' => 2, 'quantity' => 1],
          ],
          ['products.*.product_id' => 'distinct']
        );
        
        dd($validator->passes());
