In LTS releases you always have two kernel options. The problem I pointed out is that you are deliberately NOT using any of them. Again, for Ubuntu 24.04 either the original branch - 6.8 - that is also a long term supported kernel, or HWE (Hardware Enablement) that is/are newer versions from newer releases backported and currently 7.0. This are your options. 6.14 or 6.17 are NOT, period.
If you are using HWE you can at any time install the other one: sudo apt install --install-recommends linux-generic
Conversely, if you installed the General Availability (GA) one - usually only the first ISO released does that, 24.04.1 will carry HWE - but want to have the newer version (support for newer hardware, other improvements, etc.) you can also do that: sudo apt install linux-generic-hwe-24.04
End of story.
