Part cooling Fan on Top Layer

Is there an option where i can say what Fan speed i want at top Layers?

I have a Filament that print very well with Part Fan speed at 35%, but the top looks best with 0%.

Use a M106 g-code by right clicking the + button on the top layer(s) to turn off the fans. Of cause it will only work good if there aren’t too many layers. Doesn’t really work well for organic models.
