Good news, if you think your display cable is the issue, you can now get it for $5 through Apple's self service repair. Same for the audio board's cable, the track pad/keyboard cable and the antennas (with varying prices). Separate IO and audio boards are had for <$50. Heck the entire M1 air logic board can be had for $370 now (assuming you return your old board). Other than literally sending schematics off for cloners to produce their own boards, I'm not sure what people could actually want done differently here for a "Self Service" repair program.

Are you referring to flexgate, ie MBP 2016-2017? Those are fused with the display assembly. Even if I had one, I'd basically need a lab to extend it, even independent shops usually don't do that repair.
