The behavior of the static policy can be fine-tuned using the `--cpu-manager-policy-options` flag.
The flag takes a comma-separated list of `key=value` policy options.
This feature can be disabled completely using the `CPUManagerPolicyOptions` feature gate.
If you disable the `CPUManagerPolicyOptions`
[feature gate](/docs/reference/command-line-tools-reference/feature-gates/)
then you cannot fine-tune CPU manager policies. In that case, the CPU manager
operates only using its default settings.
The policy options are split into two groups: alpha quality (hidden by default) and beta quality
(visible by default). The groups are guarded respectively by the `CPUManagerPolicyAlphaOptions`
In addition to the top-level `CPUManagerPolicyOptions` feature gate, the policy options are split
into two groups: alpha quality (hidden by default) and beta quality (visible by default).
The groups are guarded respectively by the `CPUManagerPolicyAlphaOptions`
and `CPUManagerPolicyBetaOptions` feature gates. Diverging from the Kubernetes standard, these
feature gates guard groups of options, because it would have been too cumbersome to add a feature
gate for each individual option.
