Is it possible to change the Hazelcast quorum configuration dynamically?

Let's say I have a Hazelcast cluster of size 7, and I defined the quorum as 4 (i.e. n / 2 + 1). Now I gracefully delete 2 nodes from the cluster, so now the cluster size is 5. In this case, I want to change the quorum size to 3. Is it possible to change the quorum size dynamically?

I want to change the quorum configuration only if the node is elegantly removed, not if the node or network partition fails, where node is still part of the cluster.
