VPN sure, but if he’s using a VPN then all visible torrent activity should be terminated at the VPN server correct? Assuming they aren’t installing management software on whatever endpoint device OP is using, how would they be able to view the specific traffic between him and whatever VPN server he is using?
In any case, I would agree with another poster that Linux ISO’s and cars to a seedbox and then transfer via SFTP would be the best route.
