I have a requirement in my project where I want to control the features based on user location. Is it possible? If yes, how can I achieve this.

Graham's answer on your other post is the right answer here: You can target by arbitrary attributes of your users, but GrowthBook does not automatically fill out these attributes, nor does it know a user's location. You would need to obtain the user's location from within your own application code, and then pass that along to GrowthBook as an attribute.
