The common dual port USB things you see on Amazon are 28mm / 1.1" and that is too large for that hole. Some of them have always on LEDs inside as well which may be annoying

You can get a smaller round and threaded on one end USB CABLE that might fit. ~1/2" for USB-C or ~3/4" for USB-A then plug the other end into a 12v-USB power supply under dash.
