from Spotfire.Dxp.Application.Visuals import *

for visual in Document.ActivePageReference.Visuals:
    if visual.TypeId == VisualTypeIdentifiers.LineChart:
        lc = visual.As[LineChart]()
    
for fm in lc.FittingModels:
    if fm.TypeId.DisplayName == "Straight Line Fit":        
        if fm.Line.DisplayName == "Straight line":
            fm.Enabled=not(fm.Enabled)
    elif fm.TypeId.DisplayName == "Exponential Curve Fit":
        print fm.Curve.DisplayName
        if fm.Curve.DisplayName == "Exponential curve":            
            fm.Enabled=not(fm.Enabled)

The other line types would include Polynomial Curve, Logarithmic Curve, Gaussian curve, etc.
