How to Send Files Between Two Android Devices Via USB

I'm part of a team working on a project where we have a small Android 12 device acting as an HID device for a host Android 12 device. The idea is that they press a button on the smaller device and that sends an F6 or F7 key event to the customer's host device which performs various functions on their end.

The issue is that we'd like to be able to push firmware/software/OS updates to this smaller device from the host device via the USB connection. Currently they are connected by two USB cables, a type A to C from host to client for the power connection, and a type A to micro usb for data on the client device's ADB port. The development team is now telling me they aren't sure it's possible.

Is there a way to push files between the two devices or is this all moot? The customer doesn't want to us Wi-Fi either as they are concerned about security as it will be used in a hospital environment.

Appreciate any advice. Thank you!

Tried connecting both devices, turned on USB debugging and file transfer on both devices. Not sure what the developers have tried as we outsourced them for this project.
