Has Apple provided an alternative?

It looks like its kIOMainPortDefault

perhaps something like...

#if (MAC_OS_X_VERSION_MAX_ALLOWED < 120000) // Before macOS 12 Monterey
  #define kIOMainPortDefault kIOMasterPortDefault
#endif

Interestingly libusb uses a simple way to do this. I am not saying it is a better way though.
https://github.com/libusb/libusb/blob/master/libusb/os/darwin_usb.c#L57

/* Both kIOMasterPortDefault or kIOMainPortDefault are synonyms for 0. */
static const mach_port_t darwin_default_master_port = 0;

This is a synonym for NULL, if you'd rather use a named constant.
