AX4-5 caching control

Can the caching on the AX4-5 be controlled or is it what it is? on AX150's i was able to set cache using navicli but i'm not so sure about this new version of the flare code. additionally can anyone tell me what the default cache settings are? since it seems that flare 6.23 does not allow cli commands at all. i don't want to have to remote into the sp to find out and at this point i'm not even sure emcremote will work.
