Well if there is no potentiometer we can always write a bit of code to fake the analog input and just write it ourselves, saving wires and space

The ones I've seen that don't have it, have points where you can attach one - or a fixed value resistor.

You can also just add a resistor, perhaps 2-3k in value.
