Total Segmentator "fast mode" cant be turned off

I am running the segmentation on a CPU and when ever I run total segmentator, and it gives me the option to run it on “fast mode” or “full resolution”, I choose full resolution but it still runs in fast mode. During the segmentation it tells me this

“No GPU detected. Running on CPU. This can be very slow. The ‘–fast’ or the --roi_subset option can help to reduce runtime.
Using ‘fast’ option: resampling to lower resolution (3mm)
Resampling…”

How can I fix this?
