NVIDIA is a major pain in the ass with Linux. Which is why I do not
use them.
Actually this is more Linux being a major pain in the ass to Nvidia.
When secure boot is enabled lockdown is automatically enabled. Really debian should provide an Nvidia package that explains the issue, sets lockdown none and runs update-grub. Unfortunately I don't believe the kernel allows just enabling raw io to even signed modules. You can look up some things like disabling debugfs to restore some of lockdowns security. I think kernel memory access is kept disabled.
