Cannot Disable Finder Integration on macOS Big Sur

I have been attempting to get Keybase to disable Finder Integration on macOS Big Sur for over an hour. If I go through the UI (Settings, Files, Disable Finder Integration) it says it's going to restart Keybase to complete the process. Then Keybase starts back up and indeed the Keybase folder shows back up on my desktop and in /Volumes. So I go into the command line and disable the kbfs service, again Keybase enables the service immediately upon launch and sets the override so that the service cannot be disabled. So I delete the entire service file, upon launching Keybase recreates it.

How on EARTH do I disable Finder Integration??

Start with the Finder Integration controls under Settings > Files and the kbfs service and service file mentioned in the report. Reproduce the behavior by disabling Finder Integration, restarting Keybase, and checking whether the Keybase folder returns in /Volumes; done means the setting remains disabled after relaunch.
