how can I exclude certain URLs from being added into Accounting Packet .

Answer 1

You cant do it on RADIUS - it only recieve that NAS sends to it. You can do in on few network access types, that uses queues to account, ie hotspots, by adding walled garden rule. But not l2tp - it sends bytes on interface.

Usual way to account this is NetFlow. It sends accounting data for each connection.
