For monsters, sure. View equipment on them has become a staple mod nowadays. Actually Equipment View uses a separate packet, which returns all item data, including private data, because devCat.
It does not even need forbidden tools to force enable equipment view. Using any memory patcher, you can simply overwrite the check that determines if the "View Equipment" option shows in the right click menu. This is how mods enable monster equipment view, for example.
Overwriting that check is all one needs to do. Nothing needs to be faked, that tool isn't needed. Just a little fiddling in RAM.
For players, no. If the player has the setting off, the server will not send the data if you ask.
