MacBook 12" SSD is not dectected

My SSD is not detected. It is an onboard 256GB SSD. I need to get stuff off of it but since it is onboard I can’t put it in an external enclosure and boot from it. Does anyone know how to fix the issue, or is there something that can be done to boot from the drive by either removing it from the logic board, or something? I know it is a long shot, but I really would like to know. Thanks
