Boolean field should not show "N/A" option when set to required

Has there been any progress on this issue? I’m encountering a similar situation where a field becomes visible and required based on a specific field selection, yet the 'N/A' option remains available. Any insights on resolving this?

I worked on a patch removing the "N/A" option from the field when conditional_fields set the form-items to required. Since this is CSR we needed to do some magic to detect the "N/A" option and hide it accordingly.

I also updated the phpstan because the CI pipeline gave me problems.
