Vostro 3471 not recognizing an M.2 SSD

Hello, all. I have a Dell Vostro 3471 that I purchased earlier this year. I decided to try and replace the spinny hard drive with an SSD. I purchased a brand new WD Blue SN570 NVMe Internal SSD (M.2 form factor.)

My machine isn't seeing it in the BIOS. Dell just replaced the motherboard, on the assumption that it is defective, however that did not resolve the problem. Any ideas?
