How to disable COD payment method based on product attribute?

Question

I want to hide COD payment method based on the Product attribute. I tried payment_method_is_active event method to disable using observer like below.

My observer file is here

public function execute(
    \Magento\Framework\Event\Observer $observer
) {
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$method = $observer->getEvent()->getMethodInstance();
$quote  = $observer->getEvent()->getQuote();
$cart = $objectManager->get('\Magento\Checkout\Model\Cart');
$items = $cart->getItems();
$disable_cod = false;
foreach ($items as $item) { 
$options = $item->getProduct()->getTypeInstance(true)->getOrderOptions($item->getProduct());
    if(array_key_exists("attributes_info",$options) && count($options['attributes_info']) >= 1)
    {
      foreach($options['attributes_info'] as $myopt)
      {
          if($myopt['label']==='E-Gift'){ // Condition i am checking
             $disable_cod = true;
          }
      }
    }
if($disable_cod){
        $this->logger->critical("Disable COD");
        if($method->getCode() === 'cashondelivery'){ 
            $this->logger->critical("Here 1");
            $result = $observer->getEvent()->getResult();
            $result->setData('is_available', false);
        }
    }else{
        $this->logger->critical("Enable COD");
    }
        
}

COD is disabling only if I have an E-Gift product only. If I have other products with E-Gift product COD is not disabling. Ultimately I need to hide the COD if at least one product including E-Gift. Please help me with this.
