You might want to enable "numa interleave" for Maria (if your instance
will use more than the memory of a single physical CPU for example), for
that you can pass the option "--numa-interleave" to mysqld_safe or
simply add "numa_interleave" in the configuration under the
"[mysqld_safe]" section.
Dont forget to install the "numactl" package before if you dont want to
end up having MariaDB to fail to (re)start as its required to enable the
"numa_interleave" option.
Its usually better to use this approach to inverleave only what you
decide to rather than forcing it system-wide on the bios.

Why? Most distro kernels have most options enabled including NUMA support.
It's a xeon server with 2 cpu and 10cores each
$ numactl --hardware
shows hardware. E.g the following from a non numa.
available: 1 nodes (0)
node 0 cpus: 0 1 2 3
node 0 size: 11905 MB
node 0 free: 437 MB

0: 10
