how to switch off hydrogen bonds in TIP4P/2005 water

Dear all,

I would like to mimic a situation where hydrogen bonds are not formed in
water. So I want to simulate water but hydrogen bonds should not be formed
(or should be weaker than normal). I would like to use TIP4P/2005 water
model for this purpose. I have a parameter file for TIP4P/2005 water. Is
there a standard way to switch off hydrogen bonds in TIP4P/2005 water?

If I reduce the charge on oxygen or reduce the charge difference between
hydrogen and oxygen, will that do the job? Should I consider about cutoff
distances also?

Thank you.
