Is there a tutorial on how to do that? I would really appreciate if you could show me one or make one, if it's not possible that's fine too. Thank you!

I have recently been learning how to create ymaps for fivem with codewalker. I need help with removing collision for a trailer without accidentally removing collision for roads/general area around it, I've tried multiple times, but every single time the roads near the trailer lose their collision too. (I've tried both moving the collision boxes underground as well as deleting them).
I even tried to painstakingly only select the collision polygons of the trailer, but alas when I streamed it in fivem, my pedal still fell through the world as well as other traffic on the roads. Any help will be much appreciated. Thank you!
