If regular overwrite methods are being used, there is no need to change any setting - regardless of standalone  IDE/SATA/SAS/NVMe or RAID IDE/SATA/SAS. 

However, if quick firmware erasure methods are desired (TCG OPAL, SATA Sanitize, SAS Sanitize, SATA SSD Secure Erase, NVMe Format ), then  IDE/SATA/SAS RAID arrays must be broken into individual disks, and NVMe disk must be standalone as well. 
 
If we are talking about Intel motherboards being set to iRST, then the array must be broken for quick firmware methods; if regular overwrite methods are alright, then there is no need to break the iRST arrays.
