Assistance in understanding algorithms nPM2100

Hello.
Please excuse these potentially silly questions, but I've been given the task of monitoring battery charge while also achieving maximum energy savings.

A wearable device is being designed based on an nRF54L15  and an three-axis, all powered by a battery 2032.

The algorithm is as follows: if there is no acceleration, the device goes to sleep and wakes up when motion is detected. The device also has a functional button that can also wake it up.

1. We are considering the option of using the shipped mode.
If the nPM2100 allows using the input only for exiting the shipped mode and even if an active level is applied to this input will not react to it in any way after exiting shipped mode, In other words, is it possible to configure this input ONLY for exiting shipped mode?

2. If I use the low power mode, is the VOUT output active and what current can it supply?

3. Is it possible to wake up the nPM2100  from hibernation mode using an external signal?
