You won't ever get NUMA enabled.

Because Ryzen 7 2700X is not a NUMA processor! :)

Only Threadripper and EPYC are.

Desktop Ryzen has a "slightly NUMA-like" thing going on, it's 
recognized as 'cache groups' in the line:
FreeBSD/SMP: 1 package(s) x 2 cache groups x 4 core(s) x 2 hardware 
threads

But it's not actual NUMA.
