FreeBSD does not contain the nouveau kernel module so there is nothing
to blacklist.

These libGL errors are from Mesa libGL, which is trying to use the
userspace part of nouveau (which is part of the Mesa project),
presumably based on Nvidia GPU's PCI ID being known to Mesa, despite there being no nouveau kernel interface available.

Since you are trying to use Nvidia's binary driver (the only one which =
works on FreeBSD), Blender should have never loaded Mesa's libGL in the=
first place - there is most likely a configuration problem here with
libglvnd, the component responsible for choosing the correct libGL
implementation.

When Blender fails to detect CUDA this has nothing to do with libGL and absolutely nothing to do with nouveau - have you found any other CUDA
program to work in linux compat?
