By implementing in Openstack you mean that there should be a default allocation pool for the subnet which excludes the gateway IP? The api-ref says so (https://docs.openstack.org/api-ref/network/v2/index.html?expanded=create-subnet-detail#id279 ), not sure if this is exactly what you need:
" If allocation_pools are not specified, OpenStack Networking automatically allocates pools for covering all IP addresses in the CIDR, excluding the address reserved for the subnet gateway by default."
