I Can a qubit have a finite number of ontic states in an epistemic model?

[msumm21]

I'm reading the following paper.
https://arxiv.org/abs/1409.1570

Is there an epistemic model of a qubit in which the number of ontic states is finite? I realize Spekkens toy bit discussed in the paper has only 4 ontic states, but it seems to only model a qubit that was prepared in one of 3 quantum states and is not representative of qubit in general.

Is there either another model like Spekkens that does represent a full blown qubit or alternatively a proof that shows infinite states would be required?

I don't see how there could be since matching the predictions of QM requires modeling a continuous infinity of possible experimental outcomes.
