Actually, there is a way to disable pylint argues about the specific undefined variable(s) by specifying it in dummy-variables-rgx (or dummy-variables in the older pylint versions). dummy-variables contain _,dummy by default and overwritten with the user-specified values on pylint execution:

$ pylint --dummy-variables-rgx='(_+[a-zA-Z0-9]*?$)|dummy|host_object'

or for the older pylint versions:

$ pylint --dummy-variables='_,dummy,host_object'

Or in case of the pylint configuration for VSCode (User/Workspace Settings can be opened by pressing Ctrl + ,):

"python.linting.pylintArgs": [
    "--dummy-variables-rgx='(_+[a-zA-Z0-9]*?$)|dummy|qdict'"
]
