I think that I may have misunderstood your question... if you want the
possibility of two different outputs (hence the use of tags) you'll need to
use different book blocks. Paper instructions must be made on the top of
the file or on a paper block (on top of a file or at first in the paper
block).
%%Start of code
\version "2.24.0"
someMusic = \relative c'' { c8 d e f g f e d }
\book {
#(set-default-paper-size "a4" 'portrait)
\paper { #(set-paper-size "a4" 'portrait) }
\score { { \repeat unfold 16 { \someMusic } } }
} % end of book block
\book {
\paper { #(set-paper-size "a4" 'landscape) }
\score { { \repeat unfold 16 { \someMusic } } }
} % end of book block (different document)
%%EOF
