I have read you can unhook the NPP actuators and not get a CEL, but you can’t unhook the AFM valves without getting a CEL.
Well its easy to find out. Plug them back in and see if they move when you switch the exhaust modes on the car. You're over complicating this.

Pretty sure you will get a code if either the AFM or NPP is unplugged. At least on the later model Gen V stuff you do.
