Hi Rita,
Unfortunately not. The submit button is necessary to actually indicate that the survey is submitted vs saved.
Although you could possibly leverage CSS code to try to hide the button itself, you would risk hiding other submit buttons throughout LabKey, rendering it unusable.
If you are interested in setting up a survey-like form for people to fill out, you could use the Javascript API and wikis to accomplish this. Please take a look at our Javascript API Tutorial that has a working example that you can reference.
