I have a two monitor Plugable Dock but wanted to add a third. I wasn't sure if this is possible on a Mac Air with M1 or with this dock. The Plugable Triple Display Dock is out of stock so I decided to give it a try based on reviews saying there was a possibility of three. I also ordered a USB 3.0 expansion hub to give me more USB storage space as well. I plugged this into one of the new USB ports and. it worked! I almost couldn't believe how easy it was! I am now very thankful that the three display dock was out of stock - much, much more expensive than this solution!
