After discussion and investigation with Ian, marking this as verified by checking Desired Manifests from argocd app. 
Note that although the acm operator on hub is already on 2.4.2, it does not have the fix for proxy yet (agentclusterinstalls crd does not have proxy field). Thus end to end test should be redone after acm has the fix in a build.
