No I didn’t think so. Airliners, and many other planes have a dedicated autopilot disconnect on the yoke, so the pilot doesn’t need to remove hands from the yoke and throttle when on final approach, for example.
On Airbus, you need to click AP Disconnect twice, once to turn off AP and another to silence the disconnect alarm.
I don’t think it is SOP to use the AP disengage bar on the MCP. I always understood that to be a quasi-permanent full disconnect of the system, and you can’t turn AP back on with the normal AP button. I’m guessing you only use that in very specific circumstances.
So use the disconnect on the yoke.
