Fedora 35 here I come!
@wallace have you tried using GNOME Boxes? Years ago I gave up on VirtualBox partly because of issues with the kernel module and it not being updated right away.
I have many ansible and terrraform scripts to test many envs. I don't have seen same options for network isolation in Boxes. For me it's just for basic virt usages.
