Does monotone_constraints work with num_parallel_tree?

I am building a random forest via xgboost using the method described at https://xgboost.readthedocs.io/en/latest/tutorials/rf.html . Does the monotone_constraints still work in this scenario (num_boost_round = 1 and num_parallel_tree = number of trees in the random forest)?

Thank you.

Anyone has any answers? Thank you!
