Silly or Dumb question Not sure which.
Could be the same for a Vette, a way to prevent a voltage spike or spark.
Especially regarding brakes, the Vette has a random system check, that if the battery is not disconnected, problems
may occur.
I've found all settings are retained with only the window index relearn needed if the battery is disconnected.
My 2 cents is to disconnect the battery, yes for the paddle shifter and airbox/ TB, and not gamble

PS Make sure to have the door windows rolled down/ open.
Have fun
