The Readme in this repo, as well as the Microsoft launch blog post, feature a URL that redirects to the generic driver search page. The archived version of the original page points to a "preview" driver version 101.6854 but that driver reports no Cooperative Vectors support on an Intel Arc B580. The latest available driver version 101.6913 also reports no support.

Is there a newer driver version available with the Cooperative Vector preview support?
