Help with AFF a700 Ontap Configuration

Hi,

I've got a price quote for 90TB NVME SSD AFF 700. The quote includes  two very expensive ONTAP items:

1. 912 * SW,Per-0.1TB,Base Flash,02,-C.

2. 912 * ONTAP,Per-0.1TB,FlashBundle,Add-On,0P,QS

Are both items necessary? combined they are almost half of the configuration price.

Will appreciate some more info regarding the ONTAP licensing configuration/selection.

Best
