Looking at 410.57 code it still registers only 32bit linux ioctls.
Try to extract 64-bit libs from 64-bit driver *of the same version*
for Linux under /compat/linux then apply the patch in

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=206711
(it was filed after freebsd-gfx-bugs@nvidia.com proved to be a blackhole)

Caveat: I'm not using NVIDIA GPUs anymore, so the above workaround may
        no longer work.
