If you're going to the trouble of self-hosting, I'd suggest just running vaultwarden.

https://github.com/dani-garcia/vaultwarden

It's entirely compatible with the clients. It also removes a lot of "rug-pull" potential, and gives you the ability to access all the nice features (ex - multi-org, multi-user, shared vaults, totp, etc...)

Honestly - part of the reason I like Bitwarden is that if they ever go full "enshittification", it's going to be relatively easy and straight-forward to just move entirely off their projects and onto open-source forks.
