No think mode?

I'm using the Qwen 3.8 27B model in Notebook mode, and I can't find where to disable Think mode. I didn't find a switch for this in the model, and I tried modifying the instruction template as well, but I keep getting the block. Qwen can be used in two ways (in thinking mode or instruction mode), and I’m trying to somehow trigger the latter in textgen. So, how can I simply turn off thinking mode for this model?
