About the configuration setting of externalMemoryManagementEnabled

[skane1024]

I noticed there is a configuration option in INetworkProperties called m_ExternalMemoryManagementEnabled, its default value is False. I don't quite understand what it means. Does it refer to different backends using external unified memory management? I've tried setting externalMemoryManagementEnabled to True on some models, and found that several models have segment fault errors. I haven't seen this feature introduced in the documentation or test code, I just found it in the code. Is this feature usable? I hope you can help me clear up my confusion.
