Just use their OneScore app & it'll trigger you one or the other day without FD :-)
My experience - btw, am a student, when i installed Onecard app it was asking to Create FD like you, One day got a mail regarding OneScore app like ad free Credit Score for free, just tried it, as it was ad free used for few days, One fine day it showed me a limit of 15k 😂, that's where i landed with my first CC with 15k without a Job 😆
