The software scripts you install and execute on each operating system (as shown in my answer) rewrite the rEFInd configuration file to change the default operation system. rEFInd will the silently instructs the firmware to boot what ever operating system is defined as default in the rEFInd configuration file. In fact, you will use the Startup Manger to make rEFInd the default operating system to boot at startup. REFInd does not change the Startup Manager menu, except rEFInd itself will now appear in this menu. Install the software (scripts) in each operating system to choose the default operating system to boot at startup.Configure rEFInd to recognize the 3 operating systems.Install rEFInd on the 'MS-DOS (FAT)' partition.Note: The above command will move up disk1s3 and place the new partition disk1s4 last. sudo diskutil resizevolume disk1s2 999G 1 MS-DOS REFIND 200M The command for doing this is given below.

Only MacOS and Windows/Bootcamp appear in this menu.

The issue is that when I open High Sierra's 'Startup Disk' menu (in System Preferences), I do not see Ubuntu. I can boot into all three systems using the Apple Startup Manager (holding ALT during bootup).

On the second, I used Bootcamp to install Windows 10 (legacy/BIOS, not EFI), then installed Ubuntu 18.04 using this guide. I am running a 2009 MacPro (5,1) with two separate hard drives: on one, I've installed MacOS High Sierra.
