How to timeout herd's network services start for not to stop boot process ?

Hello, Guix developers! I'm so happy that OS Guix works on a new PC, cause I've tried to buy 2 laptops where wifi or even graphics did not work!
On Dell Vostro 3670, Core i5 9400, Nvidia Geforce 710 Guix works and even wifi works (but I use usb wifi adapter for better connection power).

I have inconvenience: during boot guix stops and wait for about 30 seconds on wifi connection, as on images and dmesg:

# dmesg |grep wlp

[ 174.528137] IPv6: ADDRCONF(NETDEV_CHANGE): wlp0s20f0u1: link becomes ready

I did not tried with internal wifi, but usb wifi adapter starts for soo long!

I've attached my config where I have to comment wpa_supplicant service and dhclient for resist this delay during boot. And I connect manually.

Please, can you say me how to postpone herd services networking, wpa-supplicant, dhclient and start them after slim's start or for example after 5 seconds after finish of boot process?

Also can you say how to add my bash script to autorun after boot if I do not use cron (for my future experiments)?
