I believe this depends on the executor being used. A kill request to mesos driver from the framework scheduler is delivered to the executor. The kill request by itself is not a guarantee that the task will be killed, until honored by the executor. So, it is possible that the executor can be written to achieve the "graceful" behavior you desire. The resources assigned to the task aren't reclaimed until the task is reported killed/terminated by the executor. It is possible, for example, to perform "clean up" or "checkpointing" as part of a task kill request. But, that can be tricky in terms of delaying the actual kill logistics, and therefore making the resources available.
If your question regarding a specific executor you are already using? In case you are referring to resource oversubscription feature recently introduced, those kills are determined by an entity local to the Mesos agent node. "Grace" would be majorly influenced by that entity and less by the executor.
