I am not entirely sure how you envisage that. I assume you have two fields in the form. Are you meaning that if the user selects a certain taxonomy term in one field, the other field then needs to set a certain value, and clear the choice the user makes?
If that is what you want, I am not sure a reset is needed, or even the best solution. Instead, it might be best to have Auto Submit OFF, add a submit button to the form, and then create some JavaScript that monitors the field to see a certain choice has been made, and if it is, then reset that one field, and set the required value on the other field, then the user can submit the form as usual with the button, or indeed you could have the javascript trigger the submit button for you.
That javascript would be custom and would have to be written by you. To trigger the submit, using JavaScript like (assuming the form has an ID of 1234) this:
$('.searchandfilter[data-sf-form-id="1234"]').submit();
