hide vendor registration form

Hello There
1:-In Vendor login page, the register now option also appears however, if someone register using this, they became wordpress default subscribe and not vendor.
there is of course the become a vendor link but 90% of people think filling up the registration form will make them vendor and ignore the become an vendor button. This is bad user experience and i received complaint about this

2:- After login there should be one form name personal details in that form we need name ,aadhar card, and bank details,phone ,profile photo .

kindly let us know how we can solve this
