I don't think there is any way to do so.

But If your intension is just to avoid index scan for some time, then you can use following command, which disable
indexscan 
        set enable_indexscan to off;
Once you are done with experimentation, you can execute command, which enable index scan.
        set enable_indexscan to on;
