Does dnf5 support parallel metadata downloads? How do I make it?

I'm pretty happily using dnf5 on my fedora 38. It's both a new library for dependency resolution and a new frontend, replacing dnf/libdnf (though nearly completely drop-in compatible with the CLI of dnf). It's much faster at doing things like searching the package database for words, so that's refreshing. Speaking of refreshing: Can I configure dnf5 to download metadata from different remote repositories (Fedora 38, Fedora 38, updates, Fedora 38 openh264, Fedora 38 nonfree updates, rpm fusion updates, rpm fusion non-free updates …) in parallel?
