How can i remove recently deleted messages option , i don’t want it

You can remove the Recently Deleted heading by deleting all of the messages in Recently Deleted.

But, if you delete another new message, then Recently Deleted will appear again. To make Recently Deleted go away, you will have to delete the message from Recently Deleted.

And so forth.

If you are asking how to permanently delete Recently Deleted, so that it will never appear again, this is not possible....unless you can convince Apple to have their software engineers rewrite the iOS programming code.
