Can i reset an iphone without the passcode or apple id?

I just bought an iphone second hand but i don't know the passcode or the apple id for it and i wanted to completely reset it so that i can use it. Is there any way to do it? Or can i take it somewhere where they can do it for me?

No, you need the code.

Nope.

No, that's the whole reason the activation lock exists.

No. The whole purpose of activation lock is to prevent people from reusing a stolen phone.
