When is Audio FPC Cable able to purchase?

Hi. My Steam Deck OLED's audio FPC cable might be damaged when I opened the LCD panel with tools after heating adhesives with heating gun. my Steam Deck still works normally but volume buttons (+/-) and 3.5 audio jack are not working at all. is there any plan to sell the OLED's audio FPC cable in the near future? Should I replace OLED's Audio board too? Thanks for advance.
