Contact support. If they tell you the part isn’t available, don’t expect it to become available. I broke my screen a year and a half ago and emailed support right away to get it replaced. Support told me that they would look into whether they were able(!) to provide a replacement screen; I waited 6 months for an answer to that question and never really got a solid yes or no. After I asked one last time I switched to a System76 machine. Haven’t looked back.
