Hi @woehrl01,

Thank you for taking the time to create this PR. As you mentioned, there is a similar PR in #27434 and as we mentioned there, CRDs are updated automatically once a new version is released. If we merge this change, it will be automatically removed during the next release of the Bitnami package. You will need to wait for the upstream project to release a new version with the updated CRD for this to be included in the chart.

Thanks

@jetersen @jotamartos thank you, I understand.
