You can cut that support. You will have to add another piece to maintain same strength. Prob change out lower track sections for longer tracks. Then add to bottom of door wood or aluminum box tube.

Unless your experienced don't mess with that torsion spring. They maim alot DIY ers.

If the rod with spring has no room to go up I think your limited to altering the concrete. Then I think you just saw out an appropriate portion, rip it out the pour new concrete at a level that works. You would still have to add to the door either top or bottom. unless you can order a custom size panel.
