How to show always 'z' values of choroplethmapbox without to use mouseover?

I am using choroplethmapbox map to show a map of my country using geojson to color districts.
This my relevant code:

var data = [{
    type: 'choroplethmapbox',
    legend: true,
    geojson: 'districts.geojson',
    featureidkey: 'properties.iso_name',
    locations: districts,
    z: hits,
    autocolorscale: true,
    'zmax': Math.max(hits),
	'zmin': 0,

Is there a way to always show z values fixed on each district instead to put mouse over?
