Differential Spoilers deployment during Auto Landing

Pixhawk 2.4.8, Plane 4.1 (dev).
Plane: 2.4M foamie glider.

I have setup differential spoilers in my glider using differential spoilers servo_n assignments.
Will they deploy during Autoland using parameter “LAND_FLAP_PERCNT”, or if “FLAP_1_SPEED” parameter was met?

Or the only way to achieve automatic flaps deployment during autolanding is to set Servo_n function to “Flaps_auto”?

Thanks in advance!
