I have an M1 MacBook Air with the same Thunderbolt port capability as the M2. I can use more than one external display by using a USB-C dock. This one has HDMI, 3 x USB 3.1 ports, Gigabit Ethernet & pass-through PD USB-C. I connect one external monitor to the HDMI port & the other to a USB 2 DisplayLink external video adaptor purchased in 2008 & still able to work with the M1 because the DisplayLink drivers are continually updated.
