Keyboard setup for FFXIV and chiaki4deck?

I have chiaki4deck set up and running smoothly, but I noticed it binds the ps4 controller buttons to keyboard. This makes in-game chat in FFXIV unusable with a keyboard. I've tried disabling direct chat in game and remapping the Cross button so it doesn't use Enter, but that didn't work. Does anyone have any advice for using a keyboard for in game chat through chiaki4deck?

The Steam Deck is connected to a usb-c dock plugged into the tv, with a wireless keyboard connected to the dock. The PS5 is in another room.
