is it possible to programatically "uncheck" showed layers in a folium map after rendering the map? (for performance reasons)

Question

I've run into an interesting problem with folium (python 3.95, folium 0.12.1.post1)

The following code renders the map very fast:

import folium

m = folium.Map(location=[35.11567262307692,-89.97423444615382], zoom_start=12, tiles='Stamen Terrain')

for i in range(200):
    feature_group = folium.FeatureGroup(i, show=True)
    feature_group.add_to(m)

folium.LayerControl().add_to(m)
m

However, if show is set to False, it takes much longer to render.

import folium

m = folium.Map(location=[35.11567262307692,-89.97423444615382], zoom_start=12, tiles='Stamen Terrain')

for i in range(200):
    feature_group = folium.FeatureGroup(i, show=False)
    feature_group.add_to(m)

folium.LayerControl().add_to(m)
m

The problem is, I don't want these layers shown by default. So I'm wondering if there's a way to render the map, and then automatically uncheck the layers.

Failing that, are there any other ways to deal with this performance issue?

Thanks very much for any guidance!
