This is not possible, I’m afraid.
I did try to implement that once, but doing this requires extremely tricky geometric calculations to handle all the edge cases. It’s a recipe for numerical disaster.
What the FollowerEntity component does, instead, is that it adjusts how it follows the path, but not the path itself, to try to stay a given distance away from the walls.
Technically you can use the RadiusModifier component for this, but be aware that there are a lot of edge cases it will handle badly.
