In the respective File if<cadname>.cfg of any CAD program, you can add the following sections:

[Interface]
#:VALS_S;
CallbackOptions_00=Capabilities=SupportsBADSTEP=0;SupportsQNS=0

This serves to completely deactivate QNS support for the export. An error message appears as soon as you click on Export.

[Interface]
#:VALS_S;
ExportHandlerSubFormat_00=positive
#:VALS_S;
ExportHandlerSubFormat_02=positive
#:VALS_S;
ExportHandlerSubFormat_03=positive
#:VALS_S;
ExportHandlerSubFormat_11=foreign,qns

This redirects all requests so that the file is opened without QNS.
