One solution I have

    #define.GroupQueryPrinter('GroupQueryPrinter')
    #define.RightButtonGrp('RightButtonGrp')
    ;

    formRun = dlg.dialogForm().formRun();

    queryGroupCtrl = formRun.design().controlName(#GroupQueryPrinter);
    
    if (queryGroupCtrl)
        queryGroupCtrl.controlNum(1).visible(showQryVal);
        
    queryGroupCtrl = formRun.design().controlName(#RightButtonGrp);
    
    if (queryGroupCtrl)
        queryGroupCtrl.controlNum(1).visible(showQryVal);

not recommended but for my project it works.

This hides the query value field group and the select button.
