2 Display // console logging question

I’m running a double display format, where the monitor that is console is
not really used after booting but the customer wants to have the last of the
boot information displayed on it, forever.

My current setup blanks the monitor when I got to 2 display modes. I can
then output to it no problem. What I want to do is keep the console ‘as it
was’

Is there a way to keep it up when switching to the 2 display mode?

Or… Is there a way to log the console boot information. (or is it being
logged already?) If that’s the case, then I can simply ‘cat’ the file on
the new fresh screen, effectively keeping the console for me.
