Can I change my NOC code after receiving my ITA?

[Shaily Bavishi]

Hi,

We recently received our ITA under Express Entry - CEC category.
However, while filling in the additional details, I realized that the NOC code that I mentioned previously is not the best match for my experience.
(Note : I am not the primary applicant and my experience in this job in Canada was less than a year so I don't think, I received any points for it)

I want to update my NOC code to match with the details mentioned in my Experience Letter, but I am not sure if I can do so after receiving the ITA.
Please advise.

Thanks,
Shaily
