```
For baselineCapabilitySet you can specify vCurrent, v4.19, or None.
```

Refer to `Table 3.1. Cluster capabilities baselineCapabilitySet values description` in the doc[1], `v4.19` is not supported to be set in baselineCapabilitySet, if we set baselineCapabilitySet to be v4.19, it will throw error. So above note for day-2 operation should be updated to remove v4.19.
