How to implement queueing the message in Fusion?

Options

In PUN2, there was a property called PhotonNetwork.IsMessageQueueRunning that controlled the message queue.

However, in PhotonFusion, are there any alternative properties or APIs that serve the same purpose?

When transitioning scenes and performing system initialization, I want to avoid allowing Spawn processes from other players. Is there a way to temporarily queue events/messages from other players during the initialization process?
