Rollbacks on Canadian Server

I've been encountering a fair number of rollbacks. They seem to always be on the Canadian server and can be quite costly (latest was in the boss of a juiced Iron Citadel).

I don't get these issues on the Washington server and the ping is the same. Any way to force the game to stop using the default gateways?

FYI - the bug report link posted here, but this is a POE2 issue.
