Hi Axel,
Do you mean that you'd like to filter out the contacts based on the submission values?
If yes, you can follow the next steps.
For example, there is a check box field in Contact entity named as Checkbox.
The value for the label "Yes" is 1 and for the label "No" is 0.

Then if the field is mapped into a marketing form, the submission value will be something like:

The segment can set as the following way.

The contacts submitted the form with the checkbox ticked can be filtered out.

In the same way, the unticking ones can be filtered out with the expression: SubmittedValues Does not contain "Checkbox: true".
