Delete Of Exhaust AFM Valves After Tune

I'm in the middle installing a full Stainless Works exhaust on 19 Camaro SS that comes without the mid AFM valves.
I have used the Diablosport I3 Platinum to program disable of AFM.

My question is;
Can I ''Physically'' remove the GM exhaust AFM valve unit and plug the end of the electrical connector without getting a dash error code ?
Thanks for replies

C8 Corvette Muffler Valve Simulator Connector Plug

To delete an AFM valve; Can you use these to suppress an error code on a 19 Camaro SS ?

I do not believe Diablo offers support for the FSCM or CCM where the AFM valve controls are located depending on year model.

HPtuners have full support for ECM TCM FSCM and CCM.

If you have HPTuners, and if I remember correctly, I believe you can simply turn them off here in the CCM module.
