Can I use ipad as a second monitor folllowing this guide
Use an iPad as a second display for a Mac - Apple Support
and still connecting to the third monitor via hdmi/type-c?
Thx~
You're in luck.
I could be mistaken, but I don't think Sidecar counts against the "one external display" limit. Sidecar doesn't' give you an extra hardware video output on your M2 MacBook Air, or add a hardware video input to an iPad (which has none). It uses a software-based virtual display connection.

There is apparently a limit of one Sidecar display at a time.
