To control the volume you should lower the input of the amplifier. This is usually provided by the audio source but can be also achieved by using potentiometers (analog or digital controlled).

But you can control the Raspberry Pi output volume with the amixer command line utility and the alsamixer graphical utility.

See for example Sound configuration on Raspberry Pi with ALSA[^] and amixer(1): mixer for ALSA soundcard driver - Linux man page[^].
