Hi there - if I understand your question correctly then it sounds that you are looking for an option to turn off the inset map frame from the layout view rather than simply deleting it. If that is the case then in ArcGIS Pro - the map frames show up as clickable layers on the left hand side (content pane). We can simply turn off the inset map frame that we do not want to display while exporting the map. Let us know if that helps.
Off topic: could someone show me how to turn off the insert in layout without control/alt/delete and/or shutting down the system? Thanks in advance.
