BQ40Z60: Is there a way to Auto shutdown when SMBus both lines are pulled low for 2 seconds ?

We are designing a pack using bq40z60, and want a feature that the pack can Auto shutdown when SMBus both lines are pulled low for 2 seconds.

I noticed that there is a auto sleep mode but it only turn off charge FETs, not discharge FET.

There is a Auto ship mode can be active but it turns off both FETs in a minute.

Is there anything else I should set to allow discharge FET being turned off when SMBus both lines are pulled low for 2 seconds? or few seconds but much less than a minute?

Thanks,

Zane
