No I don't expect it will be made configurable. That UUID field is
basically the libvirt vm's unique identifier, I can't really think of a
compelling reason to change it at all let alone expose it in the UI. You
can change it using virsh but it's a bit difficult, you'll need to
undefine the VM, change the UUID in the XML, then redefine it, to avoid
a libvirt collision check
