I am thinking about is that possible in any way (hardware of software) to limit a root process from accessing certain resource? I know maybe there is no existing solution, but how about a super root process? or an access restriction that only process with pid 1 can access something? or process that run on certain memory area can access something?

SELinux can limit even root from doing various things unless it takes on a specific role. And it can limit when root can take this specific role as well.
