Do we have method to not show all struct in param and return type ?

For example, I have a function with such signature
```
type NodePatchParam struct {
	ID uint `path:"id"`
	models.Node
}

func PatchNode(c *gin.Context, nodePatchParam *NodePatchParam) (*NodeResponse, error)
```

So the schemas in generated spec will show many schemas, including NodePatchParam and NodeResponse. 
What if I don't want to show these types ? How to omit these types ?
