Greetings Ashok,
Can you explain what is your exact requirement? In both transactions you will get the standard "Status Management" dialog and only after confirming in, you can equally post n confirmations after the "final" one for an Order.
Is your aim to prevent any Confirmations after Final Confirmation and status CNF? If so, then you can use User Status with a status that is Set by the final confirmation and that Forbids any confirmations.
