Supposedly, you could do something like:
echo "kernel-4.17.3-200" >/etc/dnf/protected.d/kernel.conf
That's supposed to make sure dnf doesn't remove that package. Note that
the "kernel" package is really a meta package that includes the
kernel-core, kernel-modules and whatnot. I've never relied on this
bit of dnf magic, but it's supposed to work.
I just tested it on a VM by "protecting" an old kernel and it seemed to
work (that kernel wasn't removed, even though it was old). Your mileage
may vary.
Interesting. I must look at that. It would be easy to work up into a
script.
