For the 5.19 kernel, I believe you should install the
linux-image-generic-hwe-22.04 meta package (and friends). [1] I
believe the command is:

    sudo apt install --install-recommends \
        linux-generic-hwe-22.04

For the 5.15 kernel, I believe you can remove it by removing the
linux-image-generic and linux-headers-generic meta packages.
