Limiting History step creation when using "photo:applyDevelopSettings"

I have created a plug-in to modify Radial Gradient in real time ( the advantage is I don't need to use the overlay) 

I use photo:applyDevelopSettings

Alas this creates many history steps.

How is it possible to stop too many steps from being created when using photo:applyDevelopSettings ?

p.s.

I am not using a slider to modify the mask.
