By "only one" you mean one usb-c + a second that's also used for power?
So, like e.g. the Dell XPS 13 9300 or the Microsoft Surface Laptop Studio.
(They have 1 other port on top of the M2 MBP, technically, but it's SD card slot - I doubt you had that in mind as what's misisng from the MBP).
Heck, there's also a port-free contender Craob X: https://craob.com/
And don't forget that you can always not buy the machine!
