Whilst not having a fix, I can propose a work-around that wraps a 
command to hide the metronome mark with ac:tempoChange. Any \tempo 
commands with a metronome mark are not affected.

\version "2.24.0" \include "articulate.ly" mytempoChange = 
#(define-music-function (newTempo) (ly:moment?) #{ \once \set 
Score.tempoHideNote=##t #(ac:tempoChange (if (ly:version? > '(2 25 22)) 
(ly:moment-main newTempo) newTempo)) #}) % (my scores and functions all 
use moments): { \tempo "Allegro" 4=100 c'2 2 \mytempoChange 
#(ly:make-moment 100 2) c'2 2 }
