set-global-staff-size is a top-level expression. It can be set per \book.
Thus:
(1) don't use it inside \book
(2) it works not for a mix of explicit and implicit books.

Wrap the toplevel score in a book:

\version "2.22.2"
%file NOTES.ly

NOTES = \relative c'' {
  \key d \minor \time 3/4
  a bes c d e f
}

#(set-global-staff-size 10)
\book {
  \score {
    \new Staff \NOTES
  }
}

#(set-global-staff-size 80)
\book {
 \bookOutputName "NOTES BIG"
  \score {
  \new Staff \NOTES
  }
}
