How to remove kernel 3 and add kernel 5 in centos 7 [closed]

I'm using Centos 7 and Desktop Version.

I executed this command in terminal:

>> uname -r5.6.13-1.el7.elrepo.x86_64

so I'm using kernel version 5 but when i executed this command:

>> rpm -q kernelkernel-3.10.0-1062.18.1.el7.x86_64kernel-3.10.0-1127.10.1.el7.x86_64

kernel 5 doesn't exist in kernels list!!!

I want to remove kernel 3 and add kernel 5 to kernel list.

How can i do?
