DnsChallenge - Configure different OVH provider with different configuration

Traefik Traefik v2 (latest)
,
1

Currently I have a server that I run under traefik in dnsChallenge mode with OVH as provider.

I find myself having to host a domain name that belongs to another OVH account.

How can I configure a second OVH provider and especially how can I configure it with other environment variables?

version: "3.3"

services:

  traefik:
    image: "traefik:v2.4"
    restart: always
    container_name: "traefik"
    command:
      - "--log.level=DEBUG"
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--certificatesresolvers.myresolver.acme.dnschallenge=true"
      - "--certificatesresolvers.myresolver.acme.dnschallenge.provider=ovh"
      - "--certificatesresolvers.myresolver.acme.dnschallenge.delayBeforeCheck=60"
      - "--certificatesresolvers.myresolver.acme.email=xxxxxxxxxxxxx"
      - "--certificatesresolvers.myresolver.acme.storage=/letsencrypt/acme.json"
