How high is the water level? To the top of the channel, the porcelain
tube that exits the bowl? I'm not a doctor of toiletology, but it
seems to me you could lower the water level below that with a toilet
plunger. If there are no other openings, like to a dishwasher, you
could do the same thing with sink traps.
I'm not a doctor of toiletology, but I don't think mere water can
damage pipes or toilets unless the water is high enough then when it
freezes, it pushes against something and breaks it. A half inch, an
inch of water in the bottom of a 2" passage will freeze and expand but
won't meet any resistance and will just get bigger. Like a bowl of
water will freeze and the water level will rise a little but it won't
break the bowl. If you're not sure of this, put an old bowl with
water in the freezer and see what happens.

That seems like a good idea. Maybe it was a bad idea when drain
pipes were made of metal, but everything in my house is plastic or
porcelain. I haven't read yet what the DT's say. If you shorten
yoru question to bare bones, it might be something a good plumber
would answer on the phone for no charge. 4PM (or 30/60 minutes before
closing might be a good time to call. They've finished their paper
work and sometimes have nothing to do.
