xDCI, DRD, USB gadget on VOXEL TGL

Is there any way I can use the usb gadget hardware present on my VOXEL under linux? The stock recovery is able to present a usb device when plugged into another computer and I’d really like to use this functionality for mass storage, network, and mtp gadgets as well as this gadget for emulating an iAP2 audio connection.
It seems like the hardware isn’t being initialized somewhere and I don’t know how to activate/utilize it.

I’ve never heard of gadget mode in recovery, can you show what it looks like?
