You can simple say that you do not have any prior experience of working as a financial advisor and upload that document. I did the same.
I also highlighted my other experience (working in IT on Banking & Finance domains for over 15 years) plus my 6 year effort in research (analysis of over 1500 companies) and developing multitudes quantitative models as supporting experience.
Again, the point here is the same. SEBI wants to ensure that the right people are made advisors.
