Polar Chart advanced modification of layout (canvas)

Hello plotly experts!

I’m working on a relatively simple polar chart.

The problem is that most of my data points are concentrated around the center with a group of outliers in a specific range of angles (red category).

I would like to do something like in the picture below - make a part of the circular layout to ‘go out of the basic circle’ so that all my data points fit nicely. Is there any way how to do such a thing?
