Hello Aspirant.

Hope you are doing well.

No, you cannot change it once you have paid the fee for the form because paying the fee simply means that you have attested all the correct information and don't want to change it and that the reason also for being the fee payment as the last step is this only. But if you wanna change the id proof after the fee payment just try contacting the authorities may be they'll help you much more in this and let you change it and you'll get there contact number from their site.

GOOD LUCK, STAY MOTIVATED AND HOPE THIS HELPS.

Thankyou.
