Does tidymodels now provide a means to tune classification model thresholds? I believe this was slated as an upcoming feature in the Spring of 2020. I looked around the tidymodels website, but have not seen a mention the feature.
As Julia says, there is an indirect method to do this.
We plan on making it a fully tunable parameter (like other parameters) but a few things have pushed this back but it is near the top of our development list.
