I recently looked into buying a new laptop, and found minifree.org, who supply libreboot BIOS chips.
What astounded me was that Intel post 2008 and AMD post 2011 have seperate management chips that mean essentially any motherboard is rooted at the start.
I still need to dive into the complexities (I knew about Intel ME but assumed we could get round it somehow) but we need these open chips more than ever.
AMD PSP has access to all the hardware in your machine. Now, whether the software running on it has drivers to control your ethernet hardware is another question, but if you could answer that, there wouldn't be a trust issue with these kinds of binary blobs.
