@sharma-bharat this PR update will need to be run with an associated code update on the ELM side. That PR is currently in draft form: E3SM-Project/E3SM#7182. I would like to have you test out the new setup, but it's slightly complicated by the fact E3SM is currently lagging behind the current fates tag. I'll need to create a special testing branch that brings E3SM up-to-date so that we can run with these new checks. I'll keep you posted, but I should be able to put that together in a day or so.

FYI, E3SM-Project/E3SM#7182 should be good to test against without needing a special branch now.
