If I have 2 PCI express connectors, x1 and x4, they have lines 0, 1, 2, 3, 4 and are divided (pair 0 goes to the connector x1 and the 1,2,3 on the connector X4), whether PCI express lines are independent and only the producer mobo decides which lines will go into the given connector. I do not know if I asked correctly. I mean if PCI-e is USB 2.0, and PCI-e X4 is like 4 such USB 2.0 connectors.

The basic question is whether PCI express lines are separable, i.e. can I split the PCI-e x16 interface into 16x PCI-e x1 connectors and connect 16 different periphelials? Exactly, I would like to split PCI express X4 into 2 PCI express X2, connect one nvme x2 disk to one(Corsair mp300), and to the other conector a graphic card.
