so

One PCIe x16 Gen 3 socket (for discrete graphic card)

not possible

Yes, it is, thank you again very much. 

Is there a way to convert this one PCI-E to more than one? I do not want to buy these expansion slots from eBay without asking.

So I don't think so, but you probably don't have enough power for a second card anyway.
moreover these models have the bad reputation of heating a lot, it could be worse
This graphics card model should be powerful enough, you shouldn't need to add another one
