Every Intel CPU since 2006 and every AMD CPU since 2013 has this stuff. If you care about this possible solutions are:
buy pre-2006/pre-2013 hardware;
go through some procedure to remove the ME[1];
forget x86 entirely (ARM?)
Yes, all modern AMD processors have this. But Intel processors have an equivalent ""feature"", called the Intel Management Engine (ME). So take you pick really.
