I had not asked about locking or searched Corsair features in a few months, but when I opened Google, this came up:

To enable Walk Away Auto Lock on your 2022 Lincoln Corsair Reserve, start your vehicle, press the right side selector wheel on the steering wheel to access the digital cluster, navigate to Vehicle Settings > Door Setup, and select "Walk Away Auto Lock," then choose "On". Once enabled, the vehicle will beep to confirm locking after you exit with the key fob and move away from the vehicle.
Step-by-step instructions:
Start the vehicle: With the vehicle in Park and the ignition on.
Access the digital cluster: Press the right side selector wheel on the steering wheel to access the instrument cluster.
Navigate to vehicle settings: Scroll to and select "Vehicle Settings".
Select door setup: Find and select the "Door Setup" option.
Enable Walk Away Auto Lock: Choose "Walk Away Auto Lock" and then select "On".
Confirm the settings: The system will take a moment to save the setting.
How it works:
After enabling, when you exit the vehicle with your key fob, and close all doors and the liftgate, the vehicle will beep once to indicate it has sensed your presence nearby.
When you move at least 8 feet away from the vehicle, it will beep again to confirm the doors are locked.
If you hear a series of rapid beeps for about two seconds, it means the doors have not locked, and you should check if all doors and the trunk are closed, and the key fob is not inside the vehicle.
