Yes your model has 2 DDR4 SODIMM slots 2400 mhz and you can upgrade the ssd this model has a M2 slot the service manual says maximum 512 gb this means dell did not test larger ssd's .
You coud go to crucial.com let them scan your dell system after that you get a list of compatible upgrades do note the prce of ram is quite high at the moment.

Hi, I also have the same problem, I bought a SSD Cosair MP510, 480GB, m.2 NVMe, and it's not recognized by the hardware, does exist any solution for this?
The manual states support for a SATA SSD, but the motherboard has a NVM type connection
I know because i've opened the machine with the SSD in hand
