If you are applying to a test optional school, submitting a test score is optional! If you don’t feel your score makes your application stronger, leave it off.
Clearly, for some applicants, a good score helps convey that they have a certain set of skills that will be useful in BS. That may be one useful data point for the AO. But AOs are also pretty savvy in their evaluation of applicants, even those without scores. So no, you aren’t disadvantaged.
