Hello,

You are reading it wrong:
It depends on CONSOLE_OVERRIDE_LOGLEVEL been =n, because of the « ! » 
And it is =n (according to the «  [=n] » text.

So go to menu « Console » and set «  Default console log level » to 8:SPEW
That’s for the coreboot part, for seabios I don’t know much.

Hope this helps
