The pin states are high, low, and Hi-Z. Hi-Z, or high-impedance, is achieved by setting the pin to input, with no pull-up (or pull-down).
Actually that's not enough with RP2350, must also disable the input due E9.
Well, yes, if your boutique micro needs a workaround then you're going to have to include it.
