As Axel says, water without hydrogen bonds is no longer water. The
closest thing to water without hydrogen bonds that exists in reality
is hydrogen sulfide, which is a gas at room temperature.

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?
