Your output is exactly what the default specs will produce, no more, no less.
If you want to experiment, you can try to change the width of the first layer. By making the first layer finer, it will “squeeze” the filament together and make the nozzle pattern less noticeable but it will not go completely away.
I’m using Hilbert infill for illustration purposes.
Default
Skinny
Note the greater number of nozzle strokes at the first layer.
Try this out with a simple cube primitive and see for yourself. Make it 2mm in height and you’ll use less filament. You can also clone the object multiple times if you want to test multiple settings in one print.
