But it's a mainboard knob, not a user knob, right?

Call them profiles or maybe personalities. Yes there is one set of
options from the developer creating the original port, but I'm
thinking more of bird's view variations;

* Zero impact coreboot (never writes to NVRAM)
* Normal mode (will fix NVRAM with defaults)
* Strict mode (requires NVRAM to always be correct, or will fail to
  boot. maybe also other extra checks in the code)

There could be other personalities. The point is that they are very
high level (ie. easy for every user to decide on, because they fit or
do not fit) and might control more than one Kconfig option.
