SHACL was released in July 2017, so, no, there is nothing in it to support RDF-star.

TopQuadrant supports RDF-star and we developed an extension to say that a particular property is reified using RDF-star. It is a predicate dash:reifiableBy. The shape of reified statements for the property (value of dash:reifiableBy) is specified as a SHACL Node Shape.

For more, see https://www.topquadrant.com/rdf-star/ and http://datashapes.org/reification.html
