Welcome to the forums, @Art!
Cloudflare is indeed an unavoidable part of our SaaS product infrastructure. We do believe that choice is critical in managing security, whether individually or for your teams/organizations, and so our self-hosting is of course available, sans-Cloudflare.
If Digital Ocean is an option for you, they have a nice droplet for Bitwarden, making deploying a self-hosted instance even easier.
