Can you remove or shave down a bridge diced cartilage graft? (Photo)

In a retouch my doctor put a diced fibrosis scar tissue glued together to augmentate the radix and bridge of my nose. I didn’t want him to do that and I think my bridge and radix are too high. I was wondering if you can shave down a diced graft or remove it, and if my nose will lose structure if I do that once it heals completely. II may have to reduce my tip by 1mm so it doesn’t look to pointy, but that’s it. I used to love the curve my nose had and now it’s completely straight, I hate it.
