The whole point of the Security Questions is to protect your account from Unauthorized access. If you forgot your security questions, you aren’t going to be able to gain access to your account. You MAY be able to call customer support and see if they can help you. They may have other ways to verify your identity but no guarantees.
We we cannot help you here as we are other users just like yourself that spend our time trying to help people that may be having issues get past their issues, but we have no control or access to Apple Information.
