Specify cache server using command line arguments

I don’t seem to be able to find an option to specify a cache server using command line arguments in the docs Unity - Manual: Command-line arguments.
Is this possible at all?

I’m going to necro this as it seems relevant and was never answered.

is the CacheServer enabled when using -bathcmode by default? If not, how do I enable it when using -batchmode?

We are seeing very long import times and it seems as though Unity is just importing locally.

bump - anyone knows how this works? thanks!
