Error when building lastest firmware (git clone https://github.com/adafruit/circuitpython.git)

Code/REPL

adding the line: CIRCUITPY_USB_MSC = 0
to /ports/raspberrypi/boards/pimoroni_tiny2040/mpconfigboard.mk results in a build error

Behavior

Description

Trying to disable mass storage as i need to write to the tiny 2040 using the storage module but dont want to eject every time i plug it in. Being used as an HID device so needs to be plugged into data and power of usb not just power. Have not tried any other rp2040 boards, just the tiny 2040.

Removing this line resolves the issue.
