The anti-commandeering doctrine prevents the federal government from directly compelling states to implement or enforce federal law. It has been ruled on time and time again, from 1842 when Justice Joseph Story affirmed it [1] to Justice Samuel Alito in 2018 [2].

[1] “The clause relating to fugitive slaves is found in the national Constitution, and not in that of any State. It might well be deemed an unconstitutional exercise of the power of interpretation to insist that the States are bound to provide means to carry into effect the duties of the National Government nowhere delegated or entrusted to them by the Constitution.” Prigg v. Pennsylvania https://supreme.justia.com/cases/federal/us/41/539/
[2] “Congress may not simply ‘commandeer the legislative process of the States by directly compelling them to enact and enforce a federal regulatory program.” Murphy v. National Collegiate Athletic Association https://www.oyez.org/cases/2017/16-476
