It's currently impossible to write alert rules for Prometheus vectors. https://github.com/grafana/grafana/issues/35663

Missing basic functionality like that is a dealbreaker.

Hoping to see cleaner ways to integrate across data sources, but developing that contract is going to take some time I think. In the meantime, should be able to get this supported with prometheus data source in a Grafana managed alert: https://github.com/grafana/grafana/pull/44865
