Like pretty much all music functions in ly/music-functions-init.ly .

So what try did you make? #{ \finger "3" #} is a perfectly valid Scheme
expression and should be compilable just fine wherever you can put
Scheme expressions.
For example, a LilyPond file looking like
#(display #{ \finger "3" #})
compiles just fine even if its output is not particularly legible.
