Yes you can set this in Internet Options: Go to the Security tab. For the current zone click the “Custom level…” button. In the next window, scroll about a third of the way down to “Miscellaneous > Access data sources across domains” and set it to “Enable”.

Note that this will effectively disable CORS and will not set the Origin header in the request.
