Universal BIOS Setup Automation for Multiple Laptops via USB (Disable Secure Boot, En

[Vahid]

Hello everyone,

I work with a large inventory of laptops that need to go through a standard BIOS setup before auditing. This involves manually configuring each BIOS to **disable Secure Boot** and **enable PXE Boot** for network-based operations.

### My Challenge:
Each laptop model (Toshiba, HP, Dell, Lenovo, etc.) requires manual BIOS configuration, and I’m looking for a **universal solution** that can:
- **Disable Secure Boot**.
- **Enable PXE Boot** and set it as the first boot option.
- Do this automatically on different laptop models from a USB drive.

### Here's what I’ve done so far:
1. I’ve set up a USB drive with the **UEFI Shell** to automate some tasks using a **`startup.nsh`** script (e.g., adjusting the boot order for PXE with `bcfg`).
2. I’ve used **RU.EFI** to manually modify UEFI variables on individual laptops, but this process is manual and specific to each model.
3. I’ve researched **`setup_var`**, but haven't found a working version that’s universal across multiple laptop brands/models.

### My Goal:
I’m looking for a solution that can automatically perform these BIOS/UEFI changes **across different laptop brands and models**:
- **Disable Secure Boot**.
- **Enable PXE Boot**.
- This needs to be non-interactive, as we are dealing with a large number of machines and want to avoid manually entering BIOS.

### Questions:
1. **Is there a universal tool or method that can modify UEFI/BIOS settings automatically across different brands and models?**
2. **Has anyone found a way to script BIOS changes like disabling Secure Boot and enabling PXE across multiple laptop models without manual input?**
3. **Are there any recommended tools that can achieve this automation in a non-interactive way?**

Any guidance or suggestions for tools or scripts that could work across multiple laptop models would be greatly appreciated!

Thank you in advance.
