Customizing kernel configuration

I’m trying to compile a custom kernel using this official guide, and I put config changes into kernel-local as it suggested:

CONFIG_DRM_AMDGPU=n

Unfortunately, when I do build using fedpkg local, I’ve got following error:

Error: Mismatches found in configuration files for arm64 aarch64-16k

RPM build errors:

Funny thing is that error outs # CONFIG_DRM_AMDGPU is not set while grep CONFIG_DRM_AMDGPU kernel-x86_64-fedora.config returns:

CONFIG_DRM_AMDGPU_CIK=y
CONFIG_DRM_AMDGPU=m
CONFIG_DRM_AMDGPU_SI=y
CONFIG_DRM_AMDGPU_USERPTR=y
# CONFIG_DRM_AMDGPU_WERROR is not set

I’ve tried putting # CONFIG_DRM_AMDGPU is not set into kernel-local as well as putting

%define listnewconfig_fail 0
%define configmismatch_fail 0

into kernel.spec as this guide suggested, but it didn’t help me either.
