Certainly not. Just read the text you posted.

It says that some equipment may allow to separate signal ground
and protective ground, and that in that case the two may remain
connected via a capacitor which may improve HF shielding.

It certainly doesn not say that you can disconnect protective
ground, on the contrary it does say that you must not do that.
