Can the mph that raises the rear spoiler be changed?

It keep the car from lifting at higher speeds. Probably does add some negligible drag, but that is what it is supposed to do.
Porsche put it there for a reason!

Why are you concerned with drag anyway? Are you trying for a high speed record?

In any case, if you don't want the spoiler to deploy, you probably could get inside it and disconnect the gears and while the motor would still work and therefore no CEL, it would not move.

There probably are alternate methods as some have added fixed wings and disconnected the spoiler and have no codes.
