Use the CapacityReservationPreference parameter to configure the instance to run in On-Demand capacity or to run in any open Capacity Reservation that has matching attributes (instance type, platform, Availability Zone). Use the CapacityReservationTarget parameter to explicitly target a specific Capacity Reservation or a Capacity Reservation group.
