How to test only relevant items and remove popular items from test whit Crossfold in Lenskit 3.0-M2
Question
How can I configure the crossfold task to generate test sets only with relevant items. That is, with rating values higher than the average rating of the user and do not consider the popular items?
Is it posible with lenskit-3.0?

It is not directly possible - the crossfolder does not take into account rating values.
A patch that added such capabilities would be welcome; you can also directly emit train/test sets yourself in Python or R.
