I managed to delete it manually by:

"curl -ks -H "Accept: application/json;version=37.0" -H "Content-Type: application/json" -H "Authorization: Bearer ${VCLOUD_ACCESS_TOKEN}" -X DELETE https://$VCD_HOSTNAME/cloudapi/1.0.0/entities/urn:vcloud:entity:vmware:solutions_add_on_instance:72f..."

The next problem is that the CSI 4.1 Plugin does not have a certificate session during cluster creation. I will need to find a way to add the certificate after cluster creation
