How to set location of icons svgs in deployment? (resourcesUrl)

I am using ionicons with Ionic 4 and angular. I would like to change the deployment to put the ionicons svg files into a different directory than svg/. I know how to do this in angular.json but I can't figure out how to tell ionicons about the new location.

There is a resourcesUrl property inside the ion-icon component that seems to figure in [1] if I could set it. I don't understand how to set it through so all components get the setting.

Does anyone know how to override the resourcesUrl path so I can point to a different location?
