Do not mention loading modules via loader.conf
It is generally discouraged to load graphics kernel modules via loder.conf(5).
According to kevans@, loader.conf loading Nvidia modules is fragile for UEFI on FreeBSD <= 12.1.
It might work, but those modules are large and ; the loader's staging area for
insufficient to contain kernel, Nvidia modules, and much of anything else at the same time.
Also, while here, encourage people to use sysrc to modify the contents of
rc.conf(5).
