How can I open doors/interact with vehicle while UI is hidden?

I like to play with the UI hidden (alt+U) but when I do so the boxes on the vehicle to open the doors, hood, change the drivemode etc are also hidden. And when these are hidden, I obiously can't click on them.
Is there a way to still being able to interact with these while the UI is hidden? ANd if it's possible to hide the boxes but still being able to interact with these it would even be better.
I dont know if there's a way to do that (a game setting? a mod? change something in the game files? idk)

Thanks for your help !

 

Hi, yes there is a possibility, just write input_actions.json to open or click to interact with your mod.
