Looking in the config/examples/Creality/Ender-3 Pro/CrealityV427/Configuration.h, around line 707, the MPC_AUTOTUNE, MPC_EDIT_MENU, and and MPC_AUTOTUNE_MENU options are commented out by default. I assume the Firmware builder profile is supposed to turn these on?
(ps. it’d be great if the firmware builder tool allowed you to download the configuration.h and configuration_adv.h as well as the binary)
