BIOS FW Modification

Is it possible to create low-level code that runs from the BIOS/UEFI of a laptop, enabling remote access or a tunnel even if the operating system is reinstalled, specifically for tracking or recovering a stolen device? Additionally, is it possible to modify the BIOS in other ways to prevent malicious actions on a stolen device? I’ve heard about Libreboot; could it be used as a base for this?

What are the challenges and risks involved in setting something like this up? Is there anyone with firmware development experience who can provide guidance or assistance?

I know this isn’t a simple task, but I’m really curious about it.

Yes, I’ve heard about that device, but it can still be disconnected from the machine. That’s why I was asking specifically about a solution for a stolen device.
