You can’t. Packet Tracer is just a learning tool with very basic functionalities, and not everything a real device can do was built into Packet Tracer. You can try using GNS3 or Cisco VIRL instead, but your best bet is to just get your hands on a real device (maybe from eBay or Amazon) to use as a lab.
