How to extend the Xavier power button shutdown time

I have a client who wants to extend the shutdown time of Xavier Power Button. For example, extend it to 20 seconds,is it possible?


are you using a custom carrier board? do you have the same power-on supervisor circuitry as on our devkit?

Not a custom carrier board,is AGX xavier developer kit

Have a try to modify the shutdown-fps-time-period-us in device tree to try.
