How to hide the original hover popup completely after specifying a new,fixed location for the popup?

Hi,

I have been using the code here to place the hover tooltip popup on a fixed position at the page (any pointers on how to put it at a fixed position relative the bokeh figure, ideally just below my heatmap plot, are much welcome). Although most of the tooltip popup now shows up at the fixed position I specified, there is still a small black triangle and a white circle remaining from the original tooltip that follows the mouse (see attached image). Is is possible to remove these or hide them somehow (maybe by making them transparent)?

Since I use the crosshair tooltip, I also find the mouse pointer unnecessary when hovering over the heatmap plot, is it possible to hide the the pointer as well?

Here is the code I am using to create the tooltip

    hover2 = HoverTool(tooltips="""
<div style=                "font-family: Ubuntu;
width : 200px;
position: fixed;
left: 85px;
top: 370px;
// border: 2px solid black;
// background: #f5f5f5;
padding: 10px">

    <span style="font-size: 16px;">@Shrt_Desc</span>

    <span style="font-size: 14px;"><br>@RDI{1.1} %RDI</span>

    <span style="font-size: 14px;"><br>@Grams{1.1} @Unit</span>

    </div>
        """
)

Cheers
