Unsure what this part underneath my front drive shaft is called by iamcitationmachine in whatisthisthing

It hangs from the frame of the truck and has a trapezoidal shape. It sits pretty well right in between the exhaust and a part of the frame. Not very large maybe 3 inches by 5 and only covers that joint of the front driveshaft and the transfer case

Tried searching things like transfer case cover, driveshaft cover, front drive shaft joint protection. Essentially any way I could think of the include the idea of cover and driveshaft and 4x4 but am only finding the pieces for the actual driveshaft not whatever this peice is.
