Hide Layer Browsing option and display only a POINT type under the Sketch tool in Analysis widget

[SushilPradhan2]

We have a custom widget that uses a Geo Processing service within the Analysis widget. The analysis widget contains option for Layer Browsing which we would like to hide as it's not required for our purpose. Also, the Analysis widget uses a Sketch tool with options for all type (point, polyline, polygon, etc), but we would like to keep only POINT type option in the Sketch tool. Is there a way to customise at backend?
