It it possible to change the serial port that the Witty Pi 4 L3V7 uses or disable the need for accessing a serial (knowing some functionality will be lost)? Use a software serial port? I have another hat that needs access to the primary serial port.

Witty Pi only monitors the voltage on TXD pin, it doesn't occupy the serial port. If you just need to use the serial port, go ahead and it should work out of box. We did test this scenario before.
If you really do not want Witty Pi to monitor TXD pin, and want to use another GPIO pin to do the job, you may follow this suggestion. Please notice that you still need to physically disconnect Pi's TXD pin from Witty Pi, and wire the new GPIO pin you want to use to Witty Pi.
