"Cabin vertical speed" is the rate of change of cabin altitude, i.e. of the pressure inside the pressurized cabin. IMO it is very unlikely that the advisory was caused by the pressure sensed by the anemometric system at the static ports. However, it is perhaps not impossible that an unusual pressure distribution along the forward fuselage at the location of the negative relief valve affects the operation of that valve, in the sense that it might have operated somewhat earlier or later than otherwise.
