Hello @alexxai
short answer: not possible
long answer: the IMU interrupt line (INT1) is not connected to any ESP32S3 GPIO and therefore it cannot wake up ESP32S3 from deep or light sleep. See schematics here.
That said IMU interrupt line is connected to the power on / off logic (IC PMS150 via E_TRIG) so it should be able to turn on M5PaperS3.
Thanks
