Seems like these are the default envs/config:

containers:
        - args:
            - manager
          env:
            - name: cp_enable
              value: 'false'
            - name: enable_service_security
              value: 'true'
            - name: lb_enable
              value: 'true'
            - name: lb_port
              value: '6443'
            - name: svc_enable
              value: 'true'
            - name: vip_arp
              value: 'true'
            - name: vip_cidr
              value: '32'
            - name: vip_interface
            - name: vip_leaderelection
              value: 'false'

But the official docs are in conflict with enabling the cp (?)

From the Architecture About section for doing Control Plane Load Balancing it says:

To enable control plane load balancing using IPVS, the environment variable

lb_enable

is required in the kube-vip manifest:

But in the Flags and Environment Variables:

cp_enable

Enables kube-vip control plane functionality

lb_enable

Enables IPVS LoadBalancer kube-vip ≥ 0.4.0. Adds nodes to the IPVS load balancer
