Here's an informative Congressional Research Service article on Enforcement of Court Orders Against the Executive Branch.[1]
TLDR; courts issue TRO (temporary restraining order), preliminary injunction, or permanent injunctions. Normally people comply. If the government does not comply then individuals can be found in civil contempt and the U.S. Marshals would enforce that. Civil contempt can't be pardoned.
There have been some TROs and injunctions issued but also some ignoring of them by the government (and also the supreme court has temporarily stayed at least one). I don't believe any contempt rulings (findings?) have been made, so not yet appropriate for the cops (Marshals).
