The problem is that the engine for that owners manual is not the same engine in the CTRHere is what the 2023 Civic Hatchback Owner's Manual found on the Honda owners website says about break-in...
Page 502:
During the first 600 miles (1,000 km) of operation, avoid sudden acceleration or full throttle operation so as not to damage the engine or powertrain.
Page 503:
Avoid hard braking for the first 200 miles (300 km) after purchasing your new vehicle or replacing the brake pads or rotors, to allow for proper break-in.
Very generic, so break-in is likely not a Honda concern.
