No, unfortunately you can't inspect encrypted traffic on IPS. Not supported.

Labib;

For traffic exiting a VPN tunnel, you can place the IPS sensor behind the VPN termination point so it has access to the unencrypted traffic.

There is not an option to inspect SSL encrypted traffic; you would need to rely on a host-based system such as Cisco Security Agent to assist in providing such protection.
