prevent wifi interference between two ESP32S3 devices?

[yanshay]

I'm developing some application involving two ESP32S3 devices which will be connected to wifi (and communicate with one another though I don't think it matters here).
The two devices may be placed one next to the other.

I noticed that when they are nearby communication keeps disconnecting, though not really disconnecting from WiFi, just the TCP communication fails from time to time. When I place them apart there are no issues. So I guess it's due to WiFi interference between them, conflicting channels or something like that.

Is there a way to prevent that from happening by configuring them in some way?
