Valentin, my friend, thank you so much.
If I may trouble you again, I've encountered a problem while trying to use
your method. I've applied it to a 5/4 two bar theme (similar to the case I
presented before); however, by removing the "superfluous" time signatures
the engraving breaks. I'm trying to remove those unnecessary time
signatures because they stand out.

\version "2.24.4"
makeDPercent =
#(define-music-function (duration) (ly:duration?)
"Make a double percent repeat of given duration."
(make-music 'DoublePercentEvent
'length (ly:duration-length duration)))
music = {
\new TabStaff \with {
\tabFullNotation}
\relative { \time 5/4
\repeat volta 4 {
\repeat unfold 2 {c16 c d8\5 d\5} \repeat unfold 2 {c16 c d8\5}
\repeat unfold 2 {c16 c d8\5 d\5} c16 c d8\5 <c f>4
\alternative {
{\after 4*5
\time 5/4 % if I remove this time signature the project won't
engrave.
\makeDPercent 4*10 }
{\repeat unfold 2 {c16 c d8\5 d\5} \repeat unfold 2 {c16 c d8\5}
<a d>2.~ <a d>2}
} % end alternative
} % end ritornelo\volta
} % end relative
} % end variable
\score { \music }
%\score { \unfoldRepeats \music }
Best regards,
Lucas
