Ability to adjust deflection angle in flight/Automatic reduction of control surface deflection angle at higher speeds

The title is pretty explanatory.
If we have a space plane, with a large deflection angle control surfaces, they become very erratic at high speeds (reentry/hyper-sonic speeds).
One way this can be countered is that deflection angle can be lowered at higher speeds, meaning the control surfaces aren't as responsive, Allowing the player to more easily stay in control. Basically lowering the sensitivity but for autopilot as well. Either a manual slider or an automatic system to reduce the deflection angle would be appreciated.
