From above example smayani-hdp cluster ID is: 3 ( https://172.26.125.109/api/lakes/3/servicesDetails )

Step 2 :- From the console use the below curl to remove the cluster.

curl -k -u <username>:<Password> -X DELETE https://<DPS_HOST>/api/lakes/<cluster_ID>;

Example :

curl -k -u admin:kjncsadasdcsdc -X DELETE https://172.26.125.109/api/lakes/3

Once the above is executed you should no longer see the cluster in UI.
