Guix also includes the 'iproute2' package, which includes a program
called 'ip' that can do the same kinds of jobs as 'ifconfig'.  I've
successfully used it in the past to set the MAC address of my network
devices.  IIRC, the command would be something like this:

ip link set <device> address <mac-addr>
