How to: Disable/Set WinSetMinimumSizeController

Hello, I traced a resizing issue to this controller: WinSetMinimumSizeController.

I found this code in the controller:
private void HandleCustomGetMinSizeEvent(IFrameTemplate frameTemplate)
{
Form form = frameTemplate as Form;
if (form == null)
return;
form.MinimumSize = new Size(640, 480);
}

I tried to Deactivate in an inherited controller and a View Controller with: Frame.GetController().Active["PopupWindow"] = false;

and I still cannot set the size of the window by handling the CustomizeTemplate Event using the following code:

private void DeactivateTeamAction_CustomizeTemplate(object sender, CustomizeTemplateEventArgs e)
{

if (e.Context == TemplateContext.PopupWindow)
{
Templates.PopupWindowForm form = (Templates.PopupWindowForm)e.Template;
form.MinimumSize = new System.Drawing.Size(100, 100);
form.Size = new System.Drawing.Size(420, 180);

}
}

Can you please provide an example of how I can set the popupwindow size smaller than 640x480?

Thank you.
