Do not use Argo on subdomain

Hello,

I have the subdomain sub1.domain.com and I don’t want traffic to pass through Argo, as files of hundreds of MB are downloaded.
I set a rule so that the traffic from that subdomain is not cached, but nevertheless I set a data consumption alert and it has jumped within hours of implementing it, how can I make sure that the traffic from that subdomain does not go through Argo.

Consumption in less than 24 hours

Thank you so much.
