Hello , 

since your query is not clear so I am answering it based on what I have faced if you want to change your certificate verification at the time of counseling and you want to restart with the registration process yes you are eligible to do that you can go for certificate verification and then start with the registration process and then go with the for the counselling process. 

Further if you need any other detail you can let me know in the comments section below.

I hope your query is solved.

Thank you.
