I am using Debian 11 and I am unable to switch my renderer from llvmpipe to nvidia. Please, how can I start using my nvidia graphics card so I can get back to my work using Blender??

Output of glxinfo -B:

Extended renderer info (GLX_MESA_query_renderer):
    Vendor: Mesa (0xffffffff)
    Device: llvmpipe (LLVM 11.0.1, 256 bits) (0xffffffff)

OpenGL vendor string: Mesa
OpenGL renderer string: llvmpipe (LLVM 11.0.1, 256 bits)

Ouput of nvidia-smi:

NVIDIA-SMI 535.98    Driver Version: 535.98    CUDA Version: 12.2
