I'm not certain what you mean by that, but I would guess that you want the nvme disk to show up as /dev/sda, and the USB disk(s) to show up as /dev/sd[b-z]. It is not possible to accomplish this using udev; the kernel owns the /dev/sdX device namespace, and will sequentially create devices nodes for SCSI-like block devices using that namespace. There is no way to change that using a udev rule.
