Investing 1Lakh for a Week

Hi, I am very new to the stocks scenario. So I wanted to get an advice, I will be investing 1lakh inr for a week or so, do you think TATASilver ETF will be a good buy right now, I am not looking for huge returns, any return between 3k-10k inr is fine for me. Is it feasible? Or is it a foolish idea? Please don't judge me, I have no prior knowledge of the stocks scenario🫠🙏
