Beware, this file should have .conf as suffix.

You can simply execute the postrans of the kernel-core RPM
rpm -q --scripts kernel-core-$(uname -r)
...
posttrans scriptlet (using /bin/sh):
/bin/kernel-install add 4.15.4-300.fc27.x86_64 /lib/modules/4.15.4-300.fc27.x86_64/vmlinuz || exit $?
Thus, for the running kernel:
/bin/kernel-install add $(uname -r) /lib/$(uname -r)/vmlinuz
It will regenerate the initramfs and eventually other things like the
grub.cfg.
I tested to add a /etc/dracut.conf.d/test.conf to omit a driver. It
works: the driver is no more in the initramfs.
