Negate Blueprints in certain levels?

For my game’s main menu, I have a blank level with a UI displayed across. But gameplay features implemented with Blueprints, such as the HUD and button commands created in my character Blueprint, still appear and function on this screen. Is there a way I can deactivate those kinds of things when the specific main menu level is open? If not, what alternative methods should I try to temporarily disable them? Any help is appreciated. Thanks.

Thanks for your response. This works for removing the HUD from the screen, but doesn’t disable the button-press abilities activated from the character Blueprint. Also, it seems to negate the “Remove from Parent” command that removes UI widgets from the screen, for some reason, causing menus to stack on top of each other. So I don’t think I’ll be able to use it.

Found the solution: use Game Mode Override to set the level to a game mode that doesn’t include the unwanted blueprints.
