You bypass them by plugging into the 1/4" inputs that bypass the preamps.
The XLR inputs *are* the preamps. You would need a hardware switch to jump the mic pre gainstage. It would be a bit redundant to include that with the alternate 1/4" inputs that accomplish the same thing.
Most preamps that allow you to "bypass" the preamp actually only pad down the input signal 20db and call it a day. They don't actually bypass. If you were adamant to use the XLR inputs, build a cable with a couple resistors, or use an inline attenuator.
