No, but there’s an amendment that says you don’t need such an amendment:
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.

Recent article that explains why the US Marshals would be a useful landmark:
Here’s One Big Way You’ll Know if We’re in a Presidential Dictatorship
The fundamental weakness of courts is that their orders have force only if people, including government officials, obey them.
…
[T]he increased procedural complexity of criminal contempt proceedings combined with the specter of presidential pardons renders criminal contempt an improbable recourse for the judiciary.
That leaves civil contempt, which, as noted, authorizes the imposition of fines, imprisonment, or both to compel compliance with judicial orders.
…
[T]he primary traditional function of the U.S. Marshals Service is to act as the enforcement arm of the courts.
…
Should the attorney general order the marshals and BOP not to enforce a judicial contempt order against an administration official, that would be an open repudiation of the rule of law and a plain declaration of presidential dictatorship.
So many great opportunities for light rail around here, especially because of the geographical constraints. If there were big subsidies for doing it, I think the city would get interested.
