you can install coreboot on it. https://doc.coreboot.org/ almost full open-source bios.
as an operating system you can use nixos or gentoo 

 Thanks mate 🙏

What advantages does coreboor have over the standard bios? 

 The code is open source. So you can check the code. 

 So i can be sure no third party has access in any way? Is that a problem to be aware of with standard bios?
