@MacNB fixed.
Perfect. Many thanks.
For Big Sur and later to write the labels to disk you may need to mount the system writable:
https://github.com/fxgst/writeable_root
True, but only the labels in the Preboot volume (and maybe the Recovery volume) actually matter and those are always writable I think.
The Data volume is not bootable (doesn't have boot.efi in /System/Library/CoreServices)
The System volume has a boot.efi but I don't think it's bootable.
I'll look into this one day when I get around to installing Big Sur and Monterey to my Mac Pro 2008.
One issue is that the .VolumeIcon.icns file on the System volume is a firm link to the icon on the Data volume. This makes the icon not viewable when booted into other macOS partitions so I'll probably want to fix that.
Here is the log:

Thanks for adding convert_label function.
It did not work for me as mentioned on insanelymac forum thread.
There's an error from tr :
tr: Illegal byte sequence
