Open a IE window with parm -noframemerging

So I need to assign an action to a button and open a window using the parameter-noframemerging or -nomerge.  Just need a bit of syntax assistance I believe.....

<td style="width: 185px" align="right">

                                                                               <input id="Button3" type="button"  value="MYHR" onclick="window.open('https://mytestURL.com', '_blank','height=750, width=1000, scrollbars=yes,

status=no')" style="font-weight: bold; color: white; background-color: #c00000; width: 185px; height: 54px; font-variant: normal; font-size: 20px;" />

                                    </td>
