If you look into the code of the resourcemanager webhook, you see that it would overwrite the value calculated by the presence of the label
high-availability-config.resources.gardener.cloud/type: server. Instead of2, we would have3according to the current values we are using in theControllerDeploymentSee: https://github.com/gardener/gardener/blob/ee2de9addf3f9b2842b2ba167aa3e0cca62e8dc7/pkg/resourcemanager/webhook/highavailabilityconfig/handler.go#L329
Instead I suggest to use the controller settings in this case.

As discussed off-line, this alternative relies on some detailed behaviour of the HA webhook, which makes it hard to understand.
Maybe an boolean flag to set the annotation
high-availability-config.resources.gardener.cloud/replicas: "1"is a better solution for the moment.
