@manasaj9 I am not aware of any specific settings you can change to allow this to work. Whenever I have automated the file upload button, I have done so using SendKeys or a positional mouse click on screen since the click must come from a "user". If it is not working while unattended, it likely means your workstation is locked. I have used a script to keep a machine unlocked, but you can usually also do that via policy. The latter is probably the best way to go as security would need to be involved. They would know about this policy and would have the appropriate controls in-place to ensure it is used appropriately.
