Part Number: BQ25731

Tool/software:
Hello TI team!
In my circuit, I am using the BQ25731 IC to convert the voltage of a
4s battery (ranging from 10V to 16.8V) to 20V (a part of the schematic is shown in the figure).
I am using N-channel MOSFETs CSD17579Q5A as the power switches.
Their maximum allowable Vgs is ±20V. Transistors VT23, VT24, and VT25 are not threatened by
Vgs overvoltage, but transistor VT26 appears to be constantly operating at the limit.
In this case, can I use such transistors in the 20-volt circuit?
And if yes, do I need to implement any protection for the gate-source junction of VT26?
