Back in the late 90s and early 2000s you could get a device called a "Ethernet splitter" which was basically a unpowered hub. They were stupid devices. If you plug them into modern hardware you will damage the ports because of current draw.
You can still find them on [Amazon].(https://www.amazon.com/dp/B07FCLLD1H/ref=cm_sw_r_cp_apa_i_zH9rDbC0DHC5R) Do not ever use one. IT WILL KILL the ports on the switch.
