Answer 1

OK i have got the solution and by below piece of code it is working fine now.

$order->setIsCustomerNotified(false);
$order->setStatus("your_order_status");
$historyItem = $order->addStatusHistoryComment($comment, "your_order_status");
$historyItem->setIsCustomerNotified(1)->save();
$order->save();
$order->sendOrderUpdateEmail($notify = true, $comment); 

Answer 2

We can also send order update email just using sendOrderUpdateEmail. After order save.

$order->save();
$order->sendOrderUpdateEmail($notify = true, 'Replace your comment');
