Client Authentication (mTLS) in Cli format for docker

Can I set up Client Authentication traefik in docker container/cli format?

I read Traefik TLS Documentation - Traefik and tried to write
- --tls.options.default.clientAuth.caFiles=/certificates/clientca1.crt
- --tls.options.default.clientAuth.clientAuthType=RequireAndVerifyClientCert
but it doesn't work.

This is dynamic configuration and needs to go into a dynamic config file, which is read via provider.file in the static config.
