Docker Nginx-Proxy TLS 1.2

We are currently using docker environment to run our containers. Front of containers we use Nginx-proxy (https://github.com/nginx-proxy/nginx-proxy) and https://github.com/nginx-proxy/docker-letsencrypt-nginx-proxy-companion to automate HTTPS connections via Let’s Encrypt.

Our issue is now that we want to provide TLS 1.2 sertificate to spesific domains. Thats because our customer has some arduino modems to sending data to the server. Arduino modem ip-stacks support onlyt 1.2 tls and now we are running TLS 1.3

Is there any ways to configure TLS 1.2 for lets encrypt generation via Nginx-proxy.
