Sysdig Agent Limits?

Install script for sysdig say ```\"resources\":{\"limits\":{\"cpu\":\"2000m\",\"memory\":\"1536Mi\"},\"requests\":{\"cpu\":\"600m\",\"memory\":\"512Mi\"}}```

Can we reduce the limit of cpu, or still require to use unto 2 CPU, this seems a lot when we try to run a 4cpu Kube node.
