'pkg which' is your friend (at least sometimes:-) -

$ pkg which /boot/modules/i915kms.ko
/boot/modules/i915kms.ko was installed by package drm-fbsd12.0-kmod-4.16.g20200221

I believe the recommendation is that you use the graphics/drm-kmod
meta-port, in order to get the correct version for your FreeBSD
version - and build the port, not install the package, to make sure it
is in sync with your kernel. Then add to rc.conf


- to make sure that the version from the port is the one that is
loaded (do *not* list it in loader.conf).
