This is, apparently, necessary to prevent stuck pixels. On the Adafruit breakout board for this display, VCOM can be toggled over SPI, but on the Beepy, it has to be done using a GPIO pin.

This will require either putting Beepy board-specific GPIO code in the SHARP display driver, or adding an abstraction for GPIO pins (see #159).
