MediaLive->MediaPackage LLHLS how to set partial segment duration

I am trying to newly released feature from MediaPackage v2 about LL-HLS, however, can't locate reference regards to the duration settings of the partial segment duration. Based on Apple's guide, the partial segment duration can be as low as 200ms (https://developer.apple.com/documentation/http-live-streaming/enabling-low-latency-http-live-streaming-hls), which is an important factor to lower down the latency. Can you help to point the direction if this is something can be set via MediaPackage?
