Hello and welcome to the VR forums!
Samsung offers a MicroUSB cover assembly for the Gear VR2 2016 (model that comes with USB-C).
The part # is
GH98-40349A .
I attached a picture of what it looks like.
I can't find the instructions online, but I believe you simply remove the USB-C module from the Gear VR then put in the MicroUSB module.
That being said, if you feel like you want to change it, here is a
link for the part on eBay.
Edit: Picture failed to load. When you select the link, you will see the picture of the assembly kit.
