Kickstart systemd services in %POST

I’ve been toying more with Kickstarts recently but I ran into a problem on F39. Previously with F38 iirc, I was able to simply just dump a systemd service file into the installed system in %POST, and then include the name of the service in the services section, however in F39 this behavior has appeared to have changed and now the %POST seems to execute after the services section. Is there any way to modify this behavior? Or is the only ways to achieve this just symlinking the services directly in the %POST and/or enabling them after installation?
