Reposition Colorbar plotly express / graph object Maps

Question

I am trying to move / reposition the colorbar. I overlay multiple layers of spatial data on the map, and the colorbar overlaps with eachother. I'd like to be able to reposition the colorbars.

I am using the US counties GeoJSON file from: https://eric.clst.org/tech/usgeojson/

import pandas as pd 
import geopandas as gpd
import mapbox
from plotly import graph_objs as go
from plotly.graph_objs import *

# Update with host url
df_geo = gpd.read_file('https://raw.githubusercontent.com/host')

import plotly.graph_objects as go

fig = go.Figure(go.Choroplethmapbox(geojson=df_geo['geometry'].to_json(), 
                                    locations=df_geo['NAME'], 
                                    z=df_geo['CENSUSAREA'],
                                    autocolorscale=False,
                                    colorscale="Viridis", 
                                    zmin=df_geo['CENSUSAREA'].min(), 
                                    zmax=df_geo['CENSUSAREA'].max(), 
                                    marker_line_width=0))


fig.update_layout(mapbox_style="light", 
                  mapbox_accesstoken=token,
                  mapbox_zoom=3, 
                  mapbox_center = {"lat": 37.0902, "lon": -95.7129},
                  margin={"r":0,"t":0,"l":0,"b":0})

fig.update_layout()
fig.show()
