Disable M5Stick Red LED?

I just upgraded from a 0.9.x version to 1.4. I can’t see where I disabled the LED in the old version (maybe it wasn’t supported?). I tried changing / disabling M5_LED in

/Users/jason/Source Code/OpenMQTTGateway-1.4.0/.pio/libdeps/esp32-m5stick-c-ble/M5StickC/src/utility/Config.h

I must clearly be missing something dumb…
