Finally i found a solution...

on Form Request class i just add sometimes rule on validate instance so when the product_id field not present on amount field will not validate and when present it will validate using validation rules like this:

class StoreRequest extend FormRequest
{
    protected function getValidatorInstance()
    {
        $validator = parent::getValidatorInstance();

        $validator->sometimes('amount', 'required|numeric|max_amount:product_id', function ($input) {
           return Arr::has($input, 'product_id');
        });

        return $validator;
    }
}
