program teensy 4.1 though pins?

I want to mount a usb-c on a panel. I want the 5 volts to drive electronics (including Teensy).
I want the gnd, D+, D- to program the Teensy 4.1 (not going through the micro usb connector)

I can't use an adapter cable. Paul says "We do have USB host support for the 2nd port. And the 2nd port is easily available from either side of the PCB on 5 though-hole pins." Can I program the Teensy through wires gnd D+, D-, on the usbc going to these 3 through-hole pins?

If so, how?

thanks,

Richard

You don't give us much to work with. Is the Teensy being mounted on another PCB where you could use tiny spring contact pins? Could you pick the +5v from the Vin pin on the corner of the Teensy and use a USB-C to mini-B converter? Can you provide a concept sketch?
 
Thanks for the consideration. There is a larger pc board upon which the Teensy 4/4.1 will be mounted (through hole pins of course).
The USB-C vertical connector will be mounted on the opposite side of the PC board and will extend through the chassis panel.
The 5 volts and gnd from the USB-C will drive a number of devices (one high current) and one the Teensy 4 itself.
The D+, D- will be used to program the Teensy during beta development.
I could have a usb-micro pigtail cable that connects the D+, D- to the Teensy USB-micro but I am trying to avoid that.
Unfortunately, the simplest approach appears to be to solder pins to the small D+, D- pads on the bottom of the 4.1 or the larger D+, D- pads on the 4.
I don't have room in the chassis for a micro to panel mount USB-C cable (nor do I want to run the high current through the Teensy both for the current and for noise).

thanks
