I don't think so in fact. If there was pick up effect - and there is - unplugging only makes it impossible to demonstrate.
So there is a flaw in the reasoning here supposing unplugging the guitar will prove pup have no effects.
What is meaningful here (and that's the only meaningful thing eventually) is what range of _expression_ tools we can access to.
Moving the ebow to the node of vibration increases the volume, to the point it rattles against the strings, which can desirable, or not.
Moving the Ebow toward the magnet polepieces of the pick in operation increases dramatically the volume and makes both fields interact. It produces on top of a highly distorted tone some burst of noise. Only when just passing vertically on the polepieces.
I can be desirable or not. Easy to avoid then.
All techniques can then take advantages of this palette by combining everything in wanted order. Being on top of the bridge pup doesn't do the same as being on top of the neck pup.
Being, say, 4 cm from neck pup toward bridge doesn't do the same as being43 cm from the neck pup on the neck.
And then as we all know, depending of the fretting hand and the location of the note played, we'll bring different sustained harmonics?.
My 2 cents

I think people conflate the internal distortion created by the ebow's
amplifier with it's effectiveness at driving the string.
Here's a simple test anyone can perform: Unplug your guitar and turn
on the ebow. Move the ebow around the pickups. Do you hear any
