No, because your Nginx server decrypts that TLS connection so can access the plaintext data. This is typically called encrypted-in-transit.

E2EE means that it's always encrypted from the sending device to the receiving device and nothing in the middle (including the service operator) can read it.

E2E implies that the data itself gets encrypted by the sender and is only decrypted by the receiver. With https, the "pipe" is encrypted, but the data is not and the server will get the plain-text.
