~I just saw this https://docs.tigera.io/calico/3.27/operations/ebpf/enabling-ebpf I didn't follow theses instructions to enable eBPF. I revert back:~

Copy code

rkeConfig:
    chartValues:
      rke2-calico:
        felixConfiguration:
          featureDetectOverride: ChecksumOffloadBroken=false
        installation:
          calicoNetwork:
            bgp: Disabled
      rke2-multus: {}

~~I don't know if this is correct.~~
