While not obvious this is mostly possible to do already as mentioned in this post --> #147 (comment)

This feature request is to have configuration options shown in the settings page to disable/enable the logs.

I'm not sure if this should be a global option for all script or a per script option or both. anyone want to add an opinion.

Relevant options:

-o NONE -l NONE -r NONE

 -o --output file         XML output file. Given path, similarly as paths given
                          to --log, --report, --xunit, and --debugfile, is
                          relative to --outputdir unless given as an absolute
                          path. Other output files are created based on XML
                          output files after the test execution and XML outputs
                          can also be further processed with Rebot tool. Can be
                          disabled by giving a special value `NONE`.
