Force M5Stack-Fire board detection for ESP32

Browse Source 
M5Stack-Fire board detection should be:

i2c0 = I2C(0, sda=Pin(21), scl=Pin(22)) 
if {0x68} <= set(i2c0.scan()): # IMU (MPU6886)
    return "m5stack-fire"

But there are some pin incompatibilities between ESP32 and ESP32-S3 boards that don't allow I2C scan.
