The input wire parasitic inductance, input cap size, and the speed of the hot plug all have contribution to the inrush current. There are couples ways that I can think of to suppress inrush current or potential high voltage stress on the IC.
1. Clamp input voltage by adding TVS on the input.
2. Add strapping resistor on EN pin, so the IC will start up after the input voltage is build up. It can avoid IC turning on at low Vin, which has higher inrush current.
3. MP24833A has lower current limit than MP24833, it can help to limit inrush current at start up.
