How can I tell my distro what kernel to use?

I've compiled my own kernel based on https://github.com/microsoft/WSL2-Linux-Kernel

If you have Windows 10 insider Build 18945 or above then add the kernel entry in %UserProfile%\.wslconfig file. See this link for more information https://docs.microsoft.com/en-us/windows/wsl/release-notes#build-18945. Or if you have lower than Build 18945, then you can place the new Linux kernel here %SystemRoot%\System32\lxss\tools\kernel.

I'll give that a try. Thank you!
