Fix wrong nose rocker

Hi all! New here. I just finished my first sup surfboard (8 8 31) and after the first ridings I realized I did a big mistake on the nose. Too little rocker which is leading to nose sink very often. Is it possible to fix this now? Nose is quite thick, I was thinking of making it thinner giving it more curve. Will this work? Is there any real option for fixing this issue? Thanks!
