It is anticipated the Ferrari driver will run the device for a handful of laps early in the session before removing it and focusing on preparation work for the weekend.
“I will run it, we'll see for how long,” Vettel said.
“I have seen it on the computer, (but) I haven't seen it in real life, I'll check it out later on.
“Then obviously it depends on how it feels tomorrow.”
The FIA has been working on plans for the alternative to the halo for several months, with Monza initially pencilled in for the first proper test.
The shield is a see-through screen that extends along the nose in front of the drivers and has been pushed as more visually appealing compared to the halo.
The clear screen is being developed by Italian company Isoclima, which makes products for a number of other high-profile racing series.
The FIA hopes that the shield can be readied in time for 2018, but if not, the halo will be introduced instead.
