Just sync an encrypted image if your threat model includes disgruntled employees motivated enough to mess with your account.

Could be problematic if the image is huge.

Anyone have experience with Boxcryptor? Haven't tried it since a few years ago (https://www.boxcryptor.com/en/)

You could use something like gocryptfs that encrypts at the file level

Cryptomator is another cross-platform alternative for file-level encryption: https://cryptomator.org

Also includes first-class support for cloud syncing apps.
