root ~ # eselect kernel list ... switch to new kernel ...
Available kernel symlink targets:

root ~ # eselect kernel set 2
root ~ # cd /usr/src/linux
root ~ # cp ../linux-5.4.72-gentoo/.config ... copy config from previous kernel ...
root ~ # make menuconfig ... check your new config and save ...
root ~ # make && make modules_install
root ~ # make install
Then run Grub2 configuration script
root ~ # grub-mkconfig -o /boot/grub/grub.cfg

root ~ # emerge @module-rebuild
