How to disable AssetCacheLocatorService (or blacklist AssetCaches)?

The ISP I use has a single public IP address which is shared across multiple customers (carrier grade NAT).

It seems that another one of their clients has enabled an AssetCache and this has been associated with the shared public IP.

I do not have access to any devices on this other person's network (nor would I want to as I don't know anything about their cache).

This is preventing Software Update in Mojave from working correctly and causing an error of "The request timed out". The AppStore however works fine.

As a workaround I've been downloading the updates manually but would like to know if there is any solution to this problem?

Here is the output of AssetCacheLocatorUtil (IPs / GUIDs redacted) in case that sheds any light on my issue:
