I am using AWS::ElasticLoadBalancingV2::LoadBalancer and we need to start using client certificates (i.e. mTLS / two-way TLS). Our ELB is terminating TLS connections and has a server side certificate.

Can the ELB itself be configured to enforce client authentication (by giving it a certificate for example)?

As I answered in your previous question, this is not a supported feature of AWS load balancers at this time. You have to switch to a load balancer type that supports TCP passthrough, and handle mTLS on your server.
