Can you do a MHD flash over Procede on valet mode?

I have a Procede installed, but I wanted to know if I can flash the car with MHD without removing the procede. I'm too lazy to open the the ecu to remove the wiring. Can I put the procede on valet mode and then flash it? Or should I remove the procede completely before I flash it?

If memory serves me correctly, if the Procede is in Map 0 (pass-through mode) CAN functions are turned off and thus can be flashed.

If either piggy (Procede or jB4) are hijacking the CANbus, your flasher will not be able to communicate.
