// This board has no external RTC chip -- the ICM-42607-P IMU sits at 0x68,
// the same I2C address DS3231 probing checks, so without this the IMU gets
// misidentified as a DS3231 and its unrelated registers get read/written
// as if they were time/status registers, producing a bogus, unfixable clock.
