But is it possible to get the CC register values copied automatically to memory by DMA, without the processor doing that in a ISR?

Hi,

You can use PPI to trigger the TIMER task TASKS_CAPTURE[n]. When this CAPTURE[n] task is triggered, the Counter value is copied to the CC[n] register. So with PPI you can e.g. connected a GPIOTE event to trigger the TIMER CAPTURE task.
