It is already possible to configure which resources update to ignore with customizations. https://argo-cd.readthedocs.io/en/stable/operator-manual/reconcile/ . Have you tried to use this feature?

Additionally, if you do not manage EndpointSlice manually, you can fully omit them from the watched resources. https://argo-cd.readthedocs.io/en/stable/operator-manual/declarative-setup/#resource-exclusioninclusion

I did that exclusion via resource updates rule. However, I think it's something everyone should do, thus having them hard-coded seems beneficial.
