I discovered that Canonical Livepatch is a SNAP App called canonical-livepatch.
On command-line, I discovered:
$ canonical-livepatch --help
Incorrect Usage. flag: help requested
NAME:
canonical-livepatch - canonical livepatch client
USAGE:
canonical-livepatch [global options] command [command options] [arguments...]
VERSION:
9.7.2
AUTHOR:
Canonical Livepatch Team
COMMANDS:

enable enable livepatching on the machine
disable disable livepatching on the machine
refresh immediately download and apply any available livepatch

GLOBAL OPTIONS:

To disable canonical-livepatch, I simply do:
$ sudo canonical-livepatch disable
Successfully disabled device. Removed machine-token: ################################
To enable canonical-livepatch, the command-line should write:
$ sudo canonical-livepatch enable MACHINE-TOKEN
where MACHINE-TOKEN is provided by canonical. However, I have not found a way to get MACHINE-TOKEN via command-line. It seems to be generated after Livepath is enable in the software_properties_gtk GUI and every enabling creates a unique MACHINE-TOKEN.
Update: Just discovered from this question that the MACHINE-TOKEN can be obtained from https://auth.livepatch.canonical.com/
