[CentOS] always boot from Elrepo kernel

Hello All, 

I purchased some Dell Latitude 3570 laptops. They came with Ubuntu preinstalled. ( Which I swapped for Centos7) 
I have to use Elrepo kernel on these machines to get some of the fn function keys to work. 
So I installed Elrepo's kernel-ml and selected this kernel with: 
# grub2-set-default 0 
( after disabling secure boot) 

The problem I see is that after a next kernel update, the new Centos kernel will be nr 0 and the machine will 
boot from that kernel if I tested this correctly. 

Is there a way I can enable elrepo kernel update but not the regular Centos kernel? 

Many thanks, J.
