I suspect that the only way not to use tablebase with Crafty under chessbase
interface is simply to uninstall them.

I know that in chessbase engines like Shredder5.32 there are 2 places when I can
choose if to use tablebases or not to use tablebases(one in the search and one
in the interface)

The engine parameters tell me if to use tablebases in the search and this is the
important parameter that is not available in Crafty.

The interface parameters that are common for all the engines are pondering and
tablebases and unticking tablebases only in the interface parameters can help
only engines who do not know to use tablebases(like Junior5) not to cheat by
using tablebases when the position is a tablebase position.
