Default Parking brake calibration bypass

Due to a malfunction, I had to disconnect the stuck parking brake cable in wheel 1 and disconnect the battery.
Unfortunately, after reconnecting the battery, I get the message “Apply Park Brake” and an annoying warning sound.

As I am waiting for parts, I have to drive like this, and the constant beeping is very annoying .
Do you know of any way to bypass this parking brake calibration procedure (with disconnected parking brake cable)?
Or where is the warning message speaker located? I think I'll disconnect it temporarily.
Best regards

park brake motor has to see current raise in a set amount of time you’re not fooling it

destroy the cluster speaker or live with it

If you disconnect the cable from the brake and the servo tries to tighten, it can over-travel and kill the servo. Permanent error light. Don't ask me how I know.......
