The BMS resides inside the HV battery pack's case and it externally powered by the 12v system. Disconnecting the 12v battery is the only "reset" of the BMS available outside of TPD functions.
The Service Disconnect on top of the HV battery (accessible via the floor, under the right seat) splits the battery modules' circuit in half, and that's all it does (well, it interrupts the HVIL loop, too). Removing it doesn't have any effect to reset anything. It's in series with the contactors, which are open 95% of the life of the battery.
For those reasons, I'm not going to try what you ask, as disconnecting the 12v battery + removing the HV battery Service Disconnect cannot affect the LDU's inverter communications in the way you imagine.
