How could I remove or mute the sounds that wildlife makes in a NPC spawner device?

Npc spawners are a great idea and a great addition to the UEFN toolset. But, the configurations we currrently have are not enough. I was playing with this device and the NPC definition data asset for a while, I noticed that the npc type that works with my Skeletal Mesh and creates the correct collision for it are the wildlife npc’s.

The problem

The issue with the Wildlife NPC type is that they make sounds, you can hear the board or the chicken doing some ambient noises and some damage sounds, and the wolf howls from time to time. I want to polish my game so it has the NPC but either with my own sounds or no sounds of other animals at all.
