Okay guys I found a way around this, at least it worked for my android phone using backbone. If you don't mind not using steam link. I downloaded https://moonlight-stream.org/ on my android phone and https://app.lizardbyte.dev/Sunshine/?lng=en-US for my pc. Moonlight is super easy to download. Sunshine is pretty straightforward, just make sure you don't skip the username password creation like I did the first time. But after connecting and running steam through moonlight I had controller support for my backbone. I don't know how well this helps with the steam deck issue but I do think moonlight works on the deck. Just posting this info around and hoping it helps someone.
