For one the CANbus has nothing to do with it. Blaming the CANbus for your JEEP light flicker is like blaming your Internet connection for flickers of your in house lights.
The TIPM is the component that controls your JEEP power and it applies pulsing power (PWM) to your Headlights in order to extend the life of filament bulbs and to control brightness for the DRL function. The Flicker eliminators (Capacitors) are able to smooth out the long duty cycle PWM that occurs with the engine running and the lights normal on but they won't be able to do the same with the short duty cycle that is present when DRL is on.
With a ProCal you could program out the DRL but the OPP might not like that or you can program different lights to come on instead of the Headlights (fog or flasher) which might be more OPP friendly. Other option is to use a relay after the flicker eliminator on the headlight harness and power the HID ballasts with direct power via the relay.
Edit to add: until you get it fixed it's better to always switch your lights on when driving because otherwise the flicker might kill your ballasts and HID bulbs quickly.
