No.
Doing 40Gbps data is really hard because physics. Once you get beyond about 100cm, the signal loss basically requires you to add a repeater or retimer. This has been part of the USB-C specification since the very beginning, and any cable of this length doing 40Gbps will feature a similar PCB.
Sure, but I'm trying to do 10 Gbit/s on a <1m cable. That's definitely possible passively.
The USB specs say that C-to-C cables need an e-marker for that, and A-to-B or other non-C-to-C cables need nothing at all (apart from one or two resistors in case of an A-to-C or C-to-micro-B adapter).
