disable Sync With V3
Explicitly opt-in to disabling the ability to sync with Ditto peers running any version of the SDK in the v3 series of releases.
Assuming this succeeds then this peer will only be able to sync with other peers using SDKs in the v4 series of releases. Note that this disabling of sync spreads to peers that sync with a peer that has disabled, or has (transitively) had disabled, syncing with v3 SDK peers.
Throws
Thrown if the operation fails.
