How To Connect Pixhawk 4 Dshot ESC

https://docs.px4.io/master/en/peripherals/dshot.html
““If using a Pixhawk that has ports labeled AUX and MAIN, set SYS_USE_IO=0 and connect your ESCs to the AUX-labeled outputs as though they were labeled MAIN.””

Hi, this issue has confused me. Now, can’t I mount my Dshot esc by connecting the signal cable to m1, m2 places?
