Disable/delete Keys to the map DLC? (NFS Heat)

Is there a way to remove the Keys To The Map DLC after installing it?

I recently bought NFS Heat on Steam and picked up the free DLC too. I loaded up the game. All locations are visible now. The DLC was free on Origin too, so I got it on Origin too.

I now realize the game gives me ALL the locations, activities and collectables, and I want to explore and find them myself. So I want to remove the DLC and unlock/find the locations myself (get them removed from my gps map)

But even after deleting the DLC from my Steam account it still shows the locations in-game.
Maybe because the DLC is still in my game library on Origin?

How to delete/disable the DLC on Origin??
