Yes, you ought to use PARALLEL_INDEX hint, see
It opens a separate index range scan per partition.
Consider that two preconditions should be fulfilled to deploy this access
a) the index range scan is the optimal access path b) the number of records in the range in each partition is big enough to compensate the overhead of parallel processing
