Can I point a vcpkg artifact to an azure universal artifact

[Zitrax]

So this is about vcpkg artifacts using "vcpkg activate". In my registry I can point to a url like so:

        "windows": {
            "install": {
                "unzip": "https://somewhere/gcc-10.2.0.zip",
                "sha256": "..."
            },

But at the moment I have all toolchains as azure universal artifacts. There is no way to point the registry to that? Afaik there is no direct url to download azure artifacts with, one has to use the az tool. I have to use http* URLs?
