Labeled LDA does not support alpha and beta hyperparameter optimization at this time.
How can it be implemented?

Good question. Since in Labeled LDA labels are equal to topics and serve as a "mask" that zeroes out certain topics, there's no single Dirichlet distribution that we could optimize. Maybe some kind of zero inflated model like https://www.birs.ca/workshops/2019/19w5128/files/slides_ZIGDM.pdf ? I'd be open to pull requests.
