How can we stop this dialogue box when we click on save option?

 a!buttonLayout(
              primaryButtons: {
                a!buttonWidget(
                  label: cons!ISR_TEXT_BUTTON_SAVE,
                  value: cons!ISR_TEXT_BUTTON_SAVE,
                  saveInto: {
                    a!save(local!visibility, true()),
                    a!startProcess(
                      processModel: cons!ISR_WRITE_TO_DB_FINAL_APPROVAL_PM,
                      processParameters: {
                        gsr_j_meeting_amd: local!gsrAmdMD,
                        gsr_j_meeting_study: local!gsrMD,
                        isr_j_meeting_study: local!isrMD,
                        isr_j_meeting_amendment: local!isrAmdMD,
                       
                      }
                    ),
                    a!save(ri!buttonAction, save!value),
                    a!save(ri!isrMdApproval, local!isrMD, ),
                    a!save(ri!gsrMdApproval, local!gsrMD, ),
                    a!save(ri!isrMdAmdApproval, local!isrAmdMD, ),
                    a!save(ri!gsrMdAmdApproval, local!gsrAmdMD, ),
                   
                  },
                  submit: false(),
                  style: "NORMAL",
                  validate: false(),
                 
                ),
                a!buttonWidget(
                  label: "Save AND END TASK",
                  value: cons!ISR_TEXT_BUTTON_SAVE_END_TASK,
                  saveInto: {
                    a!save(local!visibility, false()),
                    a!save(ri!buttonAction, save!value),
                    a!save(ri!isrMdApproval, local!isrMD, ),
                    a!save(ri!gsrMdApproval, local!gsrMD, ),
                    a!save(ri!isrMdAmdApproval, local!isrAmdMD, ),
                    a!save(ri!gsrMdAmdApproval, local!gsrAmdMD, ),
                   
                  },
                  submit: true(),
                  style: "PRIMARY",
                  validate: true,
                  validationGroup: cons!ISR_TEXT_BUTTON_SAVE_END_TASK,
                  confirmHeader: "Submit?",
                  confirmMessage: "Are you sure you want to Submit, decision taken cannot be changed later."
                )
              }
            ),

I am just saving the comments for later without submitting. Actually, we have two buttons one is "save" and other is "save and end task", save and end task denotes submission of the task. 

Please find the code configuration for that buttons
