How to get the LayerView style

I have a SketchViewModel for a graphics layer. When I add the layerView to it I need to change some styling at runtime.

// create a featureLayer

const featureLayer = new FeatureLayer({
url: myurl
});

map.add(featureLayer);

// create a mapview and

var view = new MapView({
map: map

/ / other stuff here

});

// Given this basic featureLayer example, I will wait for the layerView to be ready.

view.whenLayerView(featureLayer).then(function(layerView) {

How would you go about accessing and changing the style for a LayerView without

sifting through all the layers as in the example below?
});

Is there a shorter way to get to the layerview style?

// this is just an example of what I do not want to do

var maplayers = item.layer.parent.allLayers.filter(function (a) {
return a.title === "my layer";
});

var style = maplayers.items[0].sublayers.items.filter(function (a) {

// do my runtime styling work here

});
