Final root cause:

- NVIDIA 580 installed successfully.
- DKMS successfully built the kernel module.
- The module was signed with your local Secure Boot key.
- Secure Boot did not initially trust that key.
- Kernel rejected the module with: `Key was rejected by service`
- You enrolled the matching MOK certificate.
- After reboot, the kernel trusted the key.
- NVIDIA modules loaded successfully.
