Exporting cpu instruction set to kernel .config file

I have seen the config from /proc/config.gz and found that processor family
as generic x86 64.

Actually my system consists of i3 10th gen comet lake 10100 which has
integrated graphics and pci express 4.0 and also lots of new instructions
like avx2, sse4 etc.,.

The main reason of compiling source code of kernel is it detects all my
hardware and provide support for opencl, video acceleration etc.,. But I
can't find any option to select my processor especially comet lake or
atleast skylake and instead there is an option called core2 in the section
processor family.

Finally I have disabled secure boot mode in bios and compiled source code
successfully and now I am able to boot into the latest build kernel but
there is no difference in performance between old and new kernels.

I think that normal kernel shipped by the distro is generic and it doesn't
have support for latest instructions like avx2, sse4 etc.,. To get support
we must compile kernel with lots of tuning.

I have exported the modules running on system and disable others by running
the command

make localmodconfig

What I want is " is there any way to export my cpu instruction set to
kernel .config file and compile kernel and install the modules.".

If I can compile kernel source code then my Linux system will run at
extreme speeds never before.
