In my NUC are two drives, one a standard SATA SSD drive and the other is a Kingston NMVe drive. The SATA SSD drive comes up as Drive 1. Can I swap this to Drive 0 and make the NVMe drive Drive 1? Is there an option in the BIOS to do this?
You actually don't need this capability. Simply change the boot order (i.e. put the SSD above the HDD in the boot order) and you will be good to go.
