Latitude 7390 max memory

Hello.

I have a latitude 7390 and I would like to upgrade the installed memory. The pc has only 1 slot available. The maximum amount of ram that Dell says it supports is 16gb. However the CPU i5 8250u supports up to 32gb max memory as intel says. The question is: if I use a 32gb dimm will it recognise it or not? The 32gb that intel says is because it takes into account 2x16gb dimms? Has anyone tried something similar before?

Thank you in advance.
