Well, yes and no. Consider:

\new FretBoards {
  \once \override FretBoard.fret-diagram-details.dot-color = #'cyan
  a
  \once \override FretBoard.fret-diagram-details.dot-color =
    #(lambda (grob) 'red)
  bes
}

I can access the value of the first override from inside
`make-fret-diagram` , ok.

The second override does not work and I currently don't know why not.
I can access the value of this override from inside make-fret-diagram as well.
Though, it's the procedure not it's return value.
