Under folder /usr/lib/aarch64-linux-gnu/dri, is there anything related to cuda/nvidia?

lvision@lvision-desktop:~$ ls /usr/lib/aarch64-linux-gnu/dri/

tegra_dri.so is the NVIDIA driver for Jetson.

(“Tegra” is the name of the embedded NVIDIA GPU/CPU module product range for gaming and edge compute)

Are you building your own? You probably should just exclude pretty much all the other modules. You’re unlikely to ever need “r600_drv_video.so” on a Nano :-)
