You can dig up the specs with the MOBO model number. Chances are it does support UASP though if the CPU is recent.
The 1M cables should yield up to 20gbps w/ a 3.2 2x2 card / port so, you should be able to get better speeds if it's a quality cable. I think most get confused by the C connection thinking it's always going to be a 10gbps connection but, they can be wired as low as USB2 @ 40mbps and most hit 5gbps unless you find 10gbps / 20gbps / 40gbps cables specifically. Same goes for charging as you need a USB-A to get higher charging on some devices because of how they're wired internally.
I got a USB-C cable w/ a DC plug on the other end for charging my laptop on the go that has a chip in the USB end that triggers 100W charging. I had to try a couple of different cables / USB-PD plugs to get things to work properly but, it does and even can charge from a power bank as well which works like a bigger 2nd battery on the go.
