Is it possible to use Sidecar with my MacBook Pro (M1 Pro) that already has two external monitors connected to it via USB-C?
I am hoping to add my iPad Pro via Sidecar so I can use the iPad for note taking and photoshop editing using my Apple Pencil.

My impression – which could be wrong – is that you can have one AirPlay or Sidecar display in addition to whatever number of real displays your Mac supports.
Since you already have both the Mac and the iPad, I would think that you could check if the configuration works just by playing it – assuming that you meet all of the Sidecar system requirements.

a sidecar device does not provide full-motion video, it provides something closer to a rapid set of snapshots. Because the update frequency is greatly reduced, a sidecar device does not consume a display generator the way a regular display does. But it does use up your Mac's hardware video encoder/decoder circuits, so the number of sidecar devices is limited.
