Idk if Vape V3 has blink and timer/speed, but I used to set a keybind that would turn on/off Blink and Timer/speed on 1.10/110% when I was in water to catch up to people. It bypassed most servers even if NoSlowdown didn't work because I guess the anticheat simply assumed you were lagging.
Until NoSlowdown is added (if it is), I would try using this in the meantime.
