For those of you who are a little bit more adventurous - The custom CachyOS kernel is also available within a Portage overlay:

https://github.com/Szowisz/CachyOS-kernels

Which enables you to run a Gentoo based system on the kernel modified by the CachyOS kernel team through a ebuild for the official sources on GitHub.

When emerging it deals with all necessary dependency flags and configuration for you, just a little bit tinkering with USE flags required.
