 | Annotation | Type | Default | Description |
 | --- | --- | --- | --- |
+| `HCLOUD_LOAD_BALANCERS_ALGORITHM_TYPE` | `round_robin \| least_connections` | `round_robin` | Configures the Load Balancer algorithm. |
 | `HCLOUD_LOAD_BALANCERS_DISABLE_IPV6` | `bool` | `false` | Disables the use of IPv6 for the Load Balancer by default. |
 | `HCLOUD_LOAD_BALANCERS_DISABLE_PRIVATE_INGRESS` | `bool` | `false` | Disables the use of the private network for ingress by default. |
+| `HCLOUD_LOAD_BALANCERS_DISABLE_PUBLIC_NETWORK` | `bool` | `false` | Disables the public interface of the Load Balancer. |
 | `HCLOUD_LOAD_BALANCERS_ENABLED` | `bool` | `true` | Controls whether the load balancer controller of HCCM should run. |
+| `HCLOUD_LOAD_BALANCERS_HEALTH_CHECK_INTERVAL` | `duration` | `-` | Configures the time interval in seconds health checks are performed. Required when health check is enabled. |
+| `HCLOUD_LOAD_BALANCERS_HEALTH_CHECK_RETRIES` | `int` | `-` | Configures the amount of unsuccessful retries needed until a target is considered unhealthy. Required when health check is enabled. |
+| `HCLOUD_LOAD_BALANCERS_HEALTH_CHECK_TIMEOUT` | `duration` | `-` | Configures the time in seconds after an attempt is considered a timeout. Required when health check is enabled. |
 | `HCLOUD_LOAD_BALANCERS_LOCATION` | `string` | `-` | Specifies the default location where the Load Balancer will be created in. Mutually exclusive with hcloudLoadBalancersNetworkZone. |
 | `HCLOUD_LOAD_BALANCERS_NETWORK_ZONE` | `string` | `-` | Specifies the default network zone where the Load Balancer will be created in. Mutually exclusive with hcloudLoadBalancersLocation. |
+| `HCLOUD_LOAD_BALANCERS_PRIVATE_SUBNET_IP_RANGE` | `string` | `-` | Configures the IP range in CIDR block notation of the subnet to attach to. |
+| `HCLOUD_LOAD_BALANCERS_TYPE` | `string` | `lb11` | Configures the Load Balancer type this Load Balancer should be created with. |
+| `HCLOUD_LOAD_BALANCERS_USES_PROXYPROTOCOL` | `bool` | `false` | Enables the proxyprotocol for a Load Balancer service. |
 | `HCLOUD_LOAD_BALANCERS_USE_PRIVATE_IP` | `bool` | `false` | Configures the Load Balancer to use the private IP for Load Balancer server targets by default. |
