Sure, it's a package just like any other. You can use the mainline kernel PPA to get any version you like.

e.g. https://wiki.ubuntu.com/Kernel/MainlineBuilds

But it might be easier to just upgrade your system from 20.04 to 22.04 and you will automatically get a kernel higher or equal 5.19 without manual intervention (with the hwe kernel)
