Changing hovermintime on plotly.py

I’m using plotly python to plot 3d meshes. The vertices change color when the mouse pointer is hovered over it. However, since there are a large number of vertices, there’s a lag between the hover over the vertex and the actual color change. I shifted to a clientside callback which sped it up, but not enough.
So, is there any way to change the hovermintime? I’m using plotly.py and the constants.js file is present in plotly.js. I couldn’t find a similar file in plotly.py.
So, how would I change the hovermintime equivalent in plotly.py?
