Once you've booted with a newer kernel, you could uninstall older kernel packages *and* any kmod packages for those kernels.
What would that look like, in my case?
Since you've referred to "sudo yum update -y", you would also use "yum" to remove installed packages with "yum remove" (see "man yum" or the help output for details). Note that if you specify a package to remove, Yum will also try to remove any dependencies. So, if you specify an old kernel (after checking with "uname -r" that you run a newer one), it will also remove anything that depends on that kernel package.
