You just define your inflation metric to suit normally by ignoring things that have gone up more eg housing and including things that are deflating like say TV's and white goods.
Some governments might, but governments actually need this information for planning, so ones with even modest levels of transparency are unlikely to do much of it, because it would be too easy to detect if it wasn't the only count, and because it would foul their own planning if it was.

Yes, one could in theory do that, but what country specifically does that (with citations to specific supporting information)? Many countries report many different inflation indicators some designed to isolate particular contributions that add noise (either because of high seasonality or high-but-irregular volatility), but they tend to also have measures which include those figures, which tend to be the main figure.
