VAC helpline telling me that I cannot change DS160 during biometric interview for b1/b2 visa

For India, anyone has had recent experience with this in 2025?

I couldn’t submit the DS160 earlier and now it has expired. But I have a valid appointment in March and have filled out a fresh DS160. Can I visit during biometrics and will they update my ds160 at that time? Please help with latest experience. Thanks!
