Disabling unity premade script component,Disabling sealed public script component

Hello,

For my college I’m developing an VR application and for my VR Rig I also used this Unity premade Snap Turn Provider component.
The problem is, that i want to disable this component via script but if I want to getcomponent this in my Rig, it doesn’t show up or is marked as false if i write it myself. My self written Components/Scripts work as always and i dont know what to do anymore.
I saw in the “SnapTurnProvider” script, that it is a sealed public class(could that be the problem?)

Component in my VR Rig:

Trying via script:

My bet is that SnapTurnProvider is inside a namespace, can you take a look to the script and double check?
