Caddy on_demand LetsEncypt with Custom SSL On_demand

Help
1

I want to use this Config in caddy


:443 {
    tls {
        # Fetch custom certificate if available
        get_certificate http://localhost:9000/get-cert
        
        # Enable on-demand TLS for domains without custom certificates
        on_demand

        # Optional: Set ask endpoint to validate domains
        ask http://localhost:9000/validate-domain
    }
}

I want to Achieve the following using caddy:

We are implementing a solution where we automatically generate SSL certificates for customers who do not have their own custom SSL certificates. For these customers, we use Let’s Encrypt’s on-demand SSL certificates.

For customers who already provide their own custom SSL certificates, we simply utilize their existing certificates. These should be also on demand using

get_certificate http://localhost:9000/get-cert

Is it possible to host both solutions on the single instance using above caddy file?

PS: I tried doing that but, only one(ask or Get_certificate) is working.

Any Solution will be appreciated.

Thanks
