Generally speaking, it's ok. Some schools are allowed to make minor changes after duplicate checking, especially some schools have advanced duplicate checking procedures, and the contents can be modified appropriately before being sent to blind review, but some schools are not allowed to do so. This is mainly based on the specific requirements of different schools and cannot be generalized!

If the school submits the paper for review according to duplicate checking, if there are no serious mistakes in your paper, you don't need to fill in the content, but it may affect the result of blind evaluation. After the blind comments are returned, you can modify the paper according to the comments, and then you can improve what you want to add. If you think that what is not added in the paper has a great influence on the blind evaluation results, it is better to consult the relevant personnel or departments of the school!

Generally, the school will inform the paper of the time of duplicate checking. After several revisions, if you feel satisfied, you can submit it to the school for duplicate check. Generally, there will be 2-3 duplicate checks in schools, that is to say, under this regulation, the first duplicate check can not be qualified, and it can be revised and then checked without any negative impact. However, some schools only have one chance to check the duplicate, and one time is not enough, so they can only postpone graduation.
