BQ25798: Over voltage protection

Part Number: BQ25798

Tool/software:

We are considering how to protect the BQ25798 with a 30 V withstand voltage, assuming a case where a maximum of 33.6 V is applied as input voltage.
I am considering how to protect VAC1 with a zener (TFZV30B) while disconnecting the NMOS of VIN2 with the charger's own OVP.
Is there any problem with this?
