Homomorphic Encryption of MariaDB contents in Appwrite Cloud

The ability to scale is paramount and Appwrite Cloud for sure looks like a functional and profitable, viable business model. Unfortunately it's a bit like giving your users data to Firebase, neutralizing the ideals and promise of self-hosted and open source in general. I haven't thought this through, but is there a way to generate a cryptographic key upon first registration of the Appwrite Project Owner, that he or she retains in the browser (Passkey API) or a Password Manager like Proton Pass; limiting Appwrite Employees ability to grasp the contents of a MariaDB even if they wanted to? I realize most use cases, even querying, or displaying user owned data back in the app, prevent this categorically, but there is an academic concept called Homomorphic Encryption > Homomorphic encryption is a form of > encryption that allows computations to > be performed on encrypted data without > first having to decrypt it.
