Putting the kernel versions you want to keep into @world by slot will keep them from being depcleaned. E.g., if depclean wants to get rid of gentoo-sources-4.19.44 but you want to keep it, use # emerge --noreplace sys-kernel/gentoo-sources:4.19.44 Note the colon. Neil's method is better, as once you implement it you never have to do anything again.
