You can hide him by typing /opt uke 0

however, it doesn't remove him, just makes him invisible. (Note: to make him re-appear, type /opt uke 1)
Adding to what buken said, if you don't want uke to interfere with your moves press ctrl+g while ingame. From there increase the engage distance so that you are further apart from the invisible uke model. If the mod that you are playing has dq activated make sure to disable it so that when uke falls the game doesn't end.
or you can do edit it in notepad to remove uke entirely.
just change the 2 to 1
