ERROR: Unable to load the 'nvidia-drm' kernel module - CentOS 7 x86_64, version 410.78

I recently updated the kernel from 3.10.693 to 4.14.15 and found the driver didn’t work any more, i tried to reinstall the driver, and found the error on the title. I’ve found a similar topic here https://devtalk.nvidia.com/default/topic/1048189/linux/error-unable-to-load-the-nvidia-drm-kernel-module-centos-7-x86_64-version-396-54/, but I’m quite sure that the nouveau has been disabled, and my X server couldn’t start. Here is what I collected:

startx -- -logverbose 6

[  155.965490] nvidia: version magic '4.14.15-1.el7.elrepo.x86_64 SMP mod_unload modversions retpoline ' should be '4.14.15-1.el7.elrepo.x86_64 SMP mod_unload modversions '

Your kernel is compiled without retpoline support.

Hi, generix
thanks for pointing out the mistake, but I was wondering if there is a retpoline patch that I could use to fix this problem. my kernel was installed through rpm file. If there is not a patch, should I compile the kernel manually? I am not quite familiar with this area, any help would be very nice.
below is some check I’ve made:

cat /sys/devices/system/cpu/vulnerabilities/spectre_v2

Vulnerable: Minimal generic ASM retpoline

grep "RETPO\|PAGE_TABLE" /boot/config-4.14.15-1.el7.elrepo.x86_64

CONFIG_RETPOLINE=y
CONFIG_PAGE_TABLE_ISOLATION=y

but when I check this file, it seems that retpoline is enabled, could it be the mismatch between config and actual kernel?
