Some suggestions:

  1. #define NO_LOGGING 1 in a relevant place (e.g. Project.Build.cs should work)
  2. use a shipping build configuration as in shipping NO_LOGGING is set to !USE_LOGGING_IN_SHIPPING and USE_LOGGING_IN_SHIPPING is set to 0 (see https://github.com/EpicGames/UnrealEngine/blob/cdaec5b33ea5d332e51eee4e4866495c90442122/Engine/Source/Runtime/Core/Public/Misc/Build.h#L352 and https://github.com/EpicGames/UnrealEngine/blob/cdaec5b33ea5d332e51eee4e4866495c90442122/Engine/Source/Runtime/Core/Public/Misc/Build.h#L220)
  3. if you can’t use one of the above disable the log categories via config (Engine.ini), you should be able to set something like the following
[Core.Log]
global = none

see https://github.com/EpicGames/UnrealEngine/blob/cdaec5b33ea5d332e51eee4e4866495c90442122/Engine/Source/Runtime/Core/Private/Logging/LogSuppressionInterface.cpp#L622

None of the links you gave are valid. Are these changes in the DefaultEngine file?

You need to be signed into GitHub and link your Epic and GitHub accounts to access the links.

Adding the setting in DefaultEngine.ini didn’t work for me but adding into the Saved/Config/Engine.ini does. Setting the verbosity to none should only log fatal messages but for me it writes a few non fatal ones (like “LogPluginManager: Mounting plugin …” for example). Not sure why that happens I would have to look at the code first.
