Dell's specifications say you can add 2230 or 2280: M.2 2230 solid-state drive PCIe Gen3.0x4 NVMe, up to 32 Gbps Up to 256 GB M.2 2230 solid-state drive PCIe Gen4.0x4 NVMe, up to 64 Gbps Up to 256 GB M.2 2280 solid-state drive PCIe Gen4.0x4 NVMe, up to 64 Gbps Up to 4 TB   Crucial shows some compatible 2280 drives. You can go up to 4 TB. Follow the disassembly and reassembly steps in Dell's Service Manual.Look on YouTube for videos showing disassembly of your model. But, be cautious with them, as some use steps or methods that are not appropriate. Use the videos to add to your understanding of what to do, but follow the steps in Dell's manual. Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. I know many people do such work without this, but it's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard.
