No. Sentinel is for managing the availability and providing service discovery when using Redis in single instance mode (single-master/one-or-more-slaves). When using Redis in cluster mode, Sentinel isn't needed.

Why isn't sentinel needed when sharding? – Don Rhummy Aug 23 '19 at 23:54
@DonRhummy because Redis Cluster has its own failover and discovery mechanisms – Itamar Haber Aug 24 '19 at 10:21
