Ignoring mutation webhook changes with argocd

[FouedD]

Hi. I am using an assign/mutation webhook to mutate image tags to digests. I am using argocd to deploy on my GKE cluster. To solve the out of Sync issue with argocd, I ignored the changes made to my image. The problem with doing this is that when the tag or the image are modified in the Git repository, argocd does not detect the change and does not deploy the new image/tag.
I know we can add this field "managedFieldsManagers:" in argocd where we specify the manager and thus only ignore mutations/changes made by a specific manager, however the one I found for gatekeeper did not resolve the issue.
I am wondering if we can customize the manager name for the mutation webhhook with gatekeeper ?
