Please don't ignore the prompt 'uncropped'

Try using the wide angle under Composition:

Also, try using prompts like: "zoomed out", "ultra wide angle".

Your orientation can also impact cropping. For example, if you want to capture a full person, it is more likely you can do it using portrait than landscape.

Last, if something is being cut off the edge, referencing it in the prompt might help. For example, if someone's foot is being cut off, referencing feet/shoes, etc. might help.
