Regarding all nitropads and intel me

I have asked this many times, but no response, are any of the devices with tenth gen processors or newer have any network stack still active underneath the bios?

Basically, are all backdoors offline on it?

Also, one other thing, can those devices be used with no proprietary blobs for graphics or sound, etc… if they don’t have nvidia? With ath9k wifi too I might add

I wanted to confirm if you know the answer to this.

Although, your devices are mega expensive and I am out of money for that at the moment anyhow.
