Traefik backend certificate override

Question

I am using Traefik with Backends in HTTPS, i have used SNI in my entrypoint (https). When i visit a HTTPS service it works showing me the Web certificate provided in Traefik.

[entryPoints]
...
  [entryPoints.https]
  address = ":443"
    [entryPoints.https.tls]
    # Datos del certificado Web A
      [[entryPoints.https.tls.certificates]] 
      certFile = "/etc/ssl/certificado-A.crt"
      keyFile = "/etc/ssl/llave-A.key"
    # Datos del certificado Web B
      [[entryPoints.https.tls.certificates]] 
      certFile = "/etc/ssl/certificado-B.crt"
      keyFile = "/etc/ssl/llave-B.key"
    # Datos del certificado Web C, etc.

My question is, is there a way to show the Backend certificate to the user instead Traefik certificate?

For example if my Backen service has its own certificate. Thanks for your answers.
