There is no need to patch the sha of the deps in the extension itself. You can override the image vector like that in the ControllerDeployment:

apiVersion: core.gardener.cloud/v1beta1
kind: ControllerDeployment
metadata:
  name: provider-metal
type: helm
providerConfig:
  chart: foobar
  values:
    image:
      tag: sha-eef069d
    imageVectorOverwrite: |
      images:
        - name: machine-controller-manager-provider-metal
          sourceRepository: github.com/ironcore-dev/machine-controller-manager-provider-metal
          repository: ghcr.io/ironcore-dev/machine-controller-manager-provider-metal
          tag: foobar

I would suggest to only use stable version/tags in the image.yaml.

thanks, we will do it manually for now and revisit when stable is there
