How can I wire a microusb to a MIMXRT1062DVL6A?
You need to develop (or adapt an existing one) a piece of firmware called a bootloader. A bootloader reads new application firmware using some kind of communication interface (like an SD card, USB as a device, serial port, USB memory stick etc.) and places it in MCU internal flash. This applies to "all" MCUs.

If you are new to MCUs - don't start with the i.MX RT (they are one of the "biggest" and most complex MCUs on the market). Start with something simpler like an ATmega328 (without using Arduino libraries), Kinetis E or STM32L0.
