Delete Default Layout1

I am built a dynamo script that will automatically create layouts and viewports based on a user-defined key plan, but right now the default Layout1 is staying in the file and throwing off the placement of the viewports by 1 sheet. So sheet 1’s viewport gets placed on Layout1, Sheet 2’s viewport gets placed on Sheet 1, and so on. How can I delete the layout 1 before the viewport placement to avoid this issue?
