There is a dnf setting to control how many old kernels will be kept.
See man dnf.conf and installonly_limit

Personally I raise that limit, but you can set to 2.
At 2 that means that if a new kernel causing you a problem you can
boot up and choose the last working kernel.

There is also the rescue kernel that you can get rid of.
See https://discussion.fedoraproject.org/t/rescue-kernel-removal/139119

If you get rid of the rescue kernel make sure that you have a live USB =
in
case you need to repair your system.
