It seems as if Nested virt for MacOS was implemented (https://github.com/containers/libkrun/pull/288), but nested virt appears [absent on Linux](https://github.com/containers/libkrun/blob/44312fdfa105256f1988ea8cdfbde8ed1532c944/include/libkrun.h#L971). The use case here is being able to have `/dev/kvm` inside your containers started with say `podman run --runtime=krun`.
