Istio ingress gateway support tls without SNI

I am setting up istio gateway as a NLB loadbalancer service and using NLB to terminate TLS. On the istio gateway side, I have a self-signed certificate. I notice that NLB doesn’t send SNI during TLS handshake to istio gateway and that causes HTTPs requests to fail. Is there a configuration option I can make on the istio gateway side to make this work?
