The only official option to relocate the cache and change its size are two command line switches that need to be added to the Chrome shortcut. Changing Chrome's Cache size and location And some users may want to move the cache location to the RAM instead, to speed up things, get the cache auto deleted on exit or avoid to many write cycles on the system partition.

I searched up and down and could not find an option to do that.
