Thunderobot R16 2025

Hi everyone,
I recently got my hands on a brand new Thunderbot R16, which is equipped with an i9-13900HX and an RTX 5070Ti. However, I noticed that the BIOS is locked, and I’m unable to undervolt the CPU or update the microcode. I’ve also seen that the BIOS write protection is enabled, and I can’t flash it on Windows or use Setup_var.
Can I use a Pi Pico to flash the BIOS directly? Also, I think this is the BIOS chip — here's a picture for reference:



Thanks in advance for any insights!
