The comments in /usr/src/sys/conf/NOTES suggest that the name for a new kernel can be modified by including "makeoptions KERNEL=x" in the configuration file.
#makeoptions KERNEL=foo #Build kernel "foo" and install "/foo"
This does not work.
I tried twice, setting the variable to '2021011901' and 'kernel-2021011902' respectively (and removing the hash sign at the beginning of the line, obviously), but the new kernel was still installed as /boot/kernel/kernel.
> grep -rs 20210119 /boot/
Binary file /boot/kernel/kernel matches
> strings /boot/kernel/kernel | grep 20210119
