You can opt out from the Twitter App. Or enable "Limit Ad Tracking".
My current twitter install on android doesn't have the feature to disable it yet, which means that i have to follow an upgrade path that includes updating -> toggling flight mode -> opening the app (if that works) and then toggling the setting.
I cannot disable it from the web interface, or this is put under a very obtrusive description.
I doubt that changes anything for Twitter. AFAIK it doesn't stop an application doing scanning like this.
