Is it possible to add a beeper which makes sounds without using a display?

Yes. You would configure an [output_pin] config section for the MCU pin that is tied to the beeper. See this config for an example: https://github.com/rootiest/zippy-klipper_config/blob/master/machine/mini12864.cfg Here is an implementation of M300: https://github.com/rootiest/zippy-klipper_config/blob/master/macros/M300.cfg And here are some premade tones and songs: https://github.com/rootiest/zippy-klipper_config/blob/master/macros/tunes.cfg

Yes -- I wired a passive speaker to the 12864 display port (since I wasn't using it for anything else). Here's the config for the Octopus: https://github.com/simplisticton/v2-2566config/blob/main/beeper.cfg (one leg of the speaker is wired to EXP1_1, the other to GND).
