Library currently enables internal pull ups:

Adafruit_CircuitPython_MatrixKeypad/adafruit_matrixkeypad.py

Line 63 in 71feb81

pin.pull = Pull.UP

but not all boards have internal pulls.

Could surround with try/except and just silently consume the exception? Sort of like "enable internal pulls if they exist".
