Can't speak for Hetzner, but considering VPN use in Russia and China - I'd imagine most EU\US vps providers have someone's 3x-ui, remnawave or naked v2ray installed.
Plus - how are they going to detect your remnawave node sitting on 443 port? For them it's just some traffict.
And if you are worried about the amount (torrents) - you don't really need to torrent though them. You just need an access to a torrect tracker to get your magnet link and meta info.
Most default configs for 'ray have torrents locks for this very reason - you communicate with other people (seeds\peers) directly.
What about all the outgoing traffic? That's going to be hard to mask unless you have another VPN for outbound
Fedora, for example, provides torrent access (including RSS feed) for its releases: https://fedoraproject.org/torrents/45/
