Hi @neevnuv , operator supports .spec.extraConfig field which can be used for add extra configs in argocd-cm configmap. Do you think that could be an option for you?
https://argocd-operator.readthedocs.io/en/latest/reference/argocd/#extra-config

We are trying to reduce ArgoCD CRD size so we might deprecate & remove some of the less used fields like .banner in future. Let me know if you find .spec.banner field useful. You can achieve the same result by using .spec.extraConfig.

Example:

apiVersion: argoproj.io/v1alpha1
kind: ArgoCD
metadata:
  name: example-argocd
spec:
  extraConfig:
    "ui.bannercontent": "value"
    "ui.bannerurl": "value"
    "ui.bannerpermanent": "value"
    "ui.bannerposition": "value"

Hello @svghadi,
Our team uses the .spec.banner option in the Argo cr, but the extraConfig option does also work for us, so we’ll be okay either way.
You may close this issue if the banner field is planned to be deprecated in the future.
