redis_instance_configs = [

    {"url": "redis://example.com:1234/1"},
    {"url": "redis://other.host:5678/2"},
]

with Lock("my_resource", redis_instance_configs):
    # do work

or speed up things for repeated use using the factory

from redlock_plus import LockFactory

redlock_factory = LockFactory(
    [
        {"url": "redis://localhost/0"},
        {"url": "redis://localhost/1"},
        {"url": "redis://localhost/2"},
    ]
)

with redlock_factory("my_resource"):
    # do work
