How to find and sign nvidia driver?

 To find and sign NVIDIA drivers on Linux, especially if you're dealing with secure boot or driver verification requirements, you'll need to obtain the NVIDIA driver package, sign it with a trusted Secure Boot key, and load it into the Secure Boot database. Here's a high-level overview of the process: 1. **Download NVIDIA Drivers:**    - Visit the official NVIDIA website to download the Linux drivers for your GPU. Make sure to download the correct driver version for your hardware. 2. **Prepare Your System:**    - Ensure that your system is set up for Secure Boot, if required.

The process can vary depending on your distribution. You can use the `openssl` command to generate a key pair. For example:      ```bash      openssl req -new -x509 -n
