Honestly I can’t remember if they outright genocided other peoples in the area, but once the Yahwists went from monolatry (worship of one god without believing that others’ gods are false) to monotheism, iirc it did cause more conflicts between ancient Israel and Judah and their neighbors. Been a while since I last actually read about this stuff

Most of the old testament is just the story of how the Israelites genocided all other peoples in the area so they could settle there.
