Actually, they are controlling your graphics driver. If you’re using a custom driver you’ll fail attestation because you have untrusted code in your kernel and/or browser process. I expect this will also fail if you’re using an old driver with known vulnerabilities that allow you to use your own device in unexpected ways.
Your TPM unit in the motherboard has more privileges than you do. It attests to the integrity of the kernel, graphics driver included, and the kernel attests to the integrity of the browser and any peripherals.
