Where to buy a U.2 -> U.2 cable?

Question

Cables and wires

There is a motherboard with a U.2 connector.
There is also an Intel Optane 900P SSD, after the purchase I found out that the bundle only comes with a U.2 -> M.2 adapter to the motherboard.
I had to connect via an adapter, but of course, I want to use the U.2 port on the motherboard directly.
We need an online store within Russia where this can be purchased.
