Disable ingress gateway with istioctl install

Hi,

Is there a way to disable the ingress-gateway ( external lb) that is created with istioctl install ? I did try
–set components.ingressGateways.enabled=false and it gave me an unmarshalling error.
istio version : 1.5.4

Background:
I wanted to install only an internal loadbalancer as the istioctl manifest installl is executed. currently, I am deleting existing service/deployment and then applying the ingress related yamls with the internal lb annotations. I bet there is an easier way and I am completely overlooking this.

Appreciate any help on this.
