The purpose being for "partial panel" practice.

To my knowledge there's nothing illegal about practicing partial panel in real IFR, however it's a spectacularly bad idea to do so. A failure of vacuum instruments in IMC is an emergency because you can easily lose orientation and dig a big hole in the ground. A safety pilot won't be able to help unless they have a separate set of instruments to rely on, and even then upset recovery in IMC is inherently less safe.
If you want to practice partial panel pleeeeease do so in VMC, with a safety pilot.

14 CFR 91.205(a) states (emphasis added):
(a) General. Except as provided in paragraphs (c)(3) and (e) of this section, no person may operate a powered civil aircraft with a standard category U.S. airworthiness certificate in any operation described in paragraphs (b) through (f) of this section unless that aircraft contains the instruments and equipment specified in those paragraphs (or FAA-approved equivalents) for that type of operation, and those instruments and items of equipment are in operable condition.
So the question is: if an instrument is covered, then is it "in operable condition"?
My interpretation would be no: if an instrument is covered, then you can't see what it says, so it's not in operable condition. That would mean that, if that instrument is required for flight, then flying with it covered is illegal.
That said, someone might disagree and say that the instrument is in operable condition, because you can simply remove the cover in order to see what it says. I would disagree with that, because a covered instrument clearly does not provide the safety benefits that an uncovered instrument does.
I did a search in the FAA's "Letter of Interpretation" database, and there didn't seem to be any letters about whether or not a covered-up instrument is "in operable condition". So it seems like this question hasn't been legally decided yet.
