My M1 Pro drives 4 screens no problem. The trick is that you can only attach two through one Thunderbolt port, so you have to attach the 3rd one via the other port instead of your dock. (The 4th screen is the laptop's built in screen)
Keyword is pro. Non-pro chips drive fewer screens unless you use DisplayLink. Which I did at some point, it's a hack but ok for lighter usage.
