Got error while installing: 

Setting config...
Enabling CachyOS config...
==> ERROR: The value cachyos is invalid. Choose the correct one again.
-> Failed to install layer, rolling up to next layer.error:error making: linux-cachyos-rc - exit status 1

But fixed it by modifying PKGBUILD file, changing "cachyos" value to the already default eevdf value.

### Selecting CachyOS config
: "${_cachy_config:=yes}"

### Selecting the CPU scheduler
# ATTENTION - only one of the following values can be selected:
# 'bore' - select 'Burst-Oriented Response Enhancer'
# 'bmq' - select 'BMQ Scheduler'
# 'hardened' - select 'BORE Scheduler hardened' ## kernel with hardened config and hardening patches with the bore scheduler
# 'cachyos' - select 'CachyOS Default Scheduler (EEVDF)'
# 'eevdf' - select 'EEVDF Scheduler'
# 'rt' - select EEVDF, but includes a series of realtime patches
# 'rt-bore' - select Burst-Oriented Response Enhancer, but includes a series of realtime patches
: "${_cpusched:=eevdf}"

And makepkg -si and it's currently building the kernel.

Edit: Compared from the yay folder linux-cachyos PKGBUILD file to the rc's PKGBUILD file, there's no $_cpusched option for cachyos in linux-cachyos-rc PKGBUILD file

### Selecting the CPU scheduler
    case "$_cpusched" in
        bore|hardened) scripts/config -e SCHED_BORE;;
        bmq) scripts/config -e SCHED_ALT -e SCHED_BMQ;;
        eevdf) ;;
        rt) scripts/config -e PREEMPT_RT;;
        rt-bore) scripts/config -e SCHED_BORE -e PREEMPT_RT;;
        *) _die "The value $_cpusched is invalid. Choose the correct one again.";;
    esac

Used updpkgsums to create new b2sum with scheduler bore selected and now it works.

enable lto-full will cause this error

lto-thin works fine.

Also enable build_nvidia will report source intergity error.

Well, either you need to build it on your own from the AUR, or the AUR Manager does that.

CachyOS repos do provide them OOB. As soon my keyring is imported into archlinux, I push it too into archlinux

The buiding process doesn't seem to fetch and build scx-scheds along with it
