Not so much in a library package where some subprograms don't have to be
used by the overall program.

You can compile with -ffunction-sections -fdata-sections which say each
subprogram/data object resp. is to have its own section. If your linker
supports (the equivalent of) -gc-sections. linking with it means that
only the used sections get linked. This is fine for (arm-eabi) embedded
systems & (probably) Linux. which use GNU ld, but not on macOS. Can't
say for Windows.

GNAT provides gnatelim, which analyses your code and (?) regenerates it
without the unused objects. No idea how well this works.
