[JLSE-Intel-NDA] disable HW prefetch on KNL

Hi, Is there a way to disable HW prefetch on KNL? For ex, on POWER8, user can use intrinsics such as __prefetch_set_dscr_register(40) to disable hw prefetch Or user can use a compiler flag to control prefetch. Is there a similar method available for KNL? regards Sudheer
