See the OP's other thread. That thread describes the OP's Mac as a 15" M3 MacBook Air.

In that thread, the OP stated that he bought a Bellini Thunderbolt dock to use three external screens with a M3 MacBook Air. (This is not the way that Thunderbolt dock display support works.)
"I buy the Bellini Thunderbolt 4 with 3 usb-c thunderbolt exit for connecting 3 screens"
Now he's talking about wanting to use two external displays with the lid open.
The M3 MacBook Air supports one external display with the lid open, two with the lid closed.
