I believe I have that, otherwise `kldload i915kms` would return 
“kldload: can’t load i915kms: No such file or directory.”

I have tried installing drivers with:

pkg install drm-kmod
pkg install drm-510-kmod
cd /usr/ports/graphics/drm-510-kmod && make install
cd /usr/ports/graphics/drm-510-kmod && make GH_TAGNAME=drm_v5.11_0 
install

My understanding is that 13.1 supports 10th gen graphics well, so I 
wouldn’t expect to need to use the absolute latest version from GitHub 
(drm_v5.11_0 in this case).
