Not that I'm aware of, but then I'm still on Fedora 36.

Well, if the problem is just due to size of the kernels, I'd expect so.

Given the right tools it's not too hard to resize, and from one of your
posts you do look like you've got one very large partition that you
could steal some space from.

On my system I've only got a few kernels kept (notice the rescue kernel
is much bigger than the rest).  I don't recall if the boot partition
size was my choice, or the installer picked that size.

My system was a fresh install, so it only has files from one system. 
If you've been upgrading over prior installs, I wonder if you have
things left over that aren't actually being used?
