Hi there,

As mentioned in the FAQ's by CCMT here

https://www.google.com/url?sa=t&source=web&rct=j&url=https://ccmt.nic.in/WebInfo/File/GetFile%3FFileId%3D14%26LangId%3DP&ved=2ahUKEwiGtvbvu5rxAhXBZSsKHQQVBakQFjAAegQIBxAC&usg=AOvVaw0ZFVYmZgK2CKR3pKkjZTCt

It is not possible.

Please make sure you fill in the category properly as you will be liable to produce the correct certificate, failing which you will be considered under the general category.

Any additional CCMT related information is available here https://engineering.careers360.com/articles/ccmt

I hope this information helps.

Good Luck!
