Ex. I like the 'Alt Supertuxkart' from the add ons, and it looks odd when I play as this kart and the standard tuxkart is an AI kart

Or to lock some more karts you have to unlock...

Just select the Add-Ons tab in the kart selection screen, and then it will only choose from that category.

but i think he wants to disable some special karts

for addon-karts it is easy, you can deinstall them, but with other you can't do that

Manually edit the respective kart.xml files to add and remove categories.
