A CloudFlare tunnel?

Although, you may also go with a 5$ virtual host (e.g. Linode Nanode 1 GB) and wireguard to build your own tunnel (or just the 5$ virtual host to run your server)

As for the volume of traffic you're sending, you need to read the terms of your ISP contract, at least a little. Your ISP could have volume limits (e.g. only 5TB of traffic per month), and if you reach those limits, they could temporarily suspend service. But if they can't see what you're doing, and you're within the technical and contractual limits of your service agreement, and you're not causing problems for them, then an ISP is not going to care what you do.
