How to set FormParser MAX_BODY_SIZE, MAX_MEMORY_FILE_SIZE?

I want to protect my system by setting MAX_BODY_SIZE, MAX_MEMORY_FILE_SIZE.

I don't know if there is a way to set it.
Is there a way to set it?

Start by locating FormParser and the MAX_BODY_SIZE and MAX_MEMORY_FILE_SIZE definitions in the project, then trace whether these limits are configurable through the public parser interface. Done should be a clear documented answer explaining how to set them, or stating that the requested configuration is not currently exposed.
