Hi Vit , yes I fixed it but it was a big job . I removed the frets and planed the fretboard away , it was not easy , the pickups were glued in . I removed the old rod , and routed a channel down the centre line and fitted a bi-flex truss rod with adjustment at the headstock . Then fitted an ebony fretboard and normal frets . If you do this wear a mask as I believe carbon fibre is not good to breath .Also note that there is no fretboard , the neck is one piece of basswood covered in C/F. You will need good skills , it is not an easy job , good luck !
