Hey thatonefemboy, unfortunately that's not possible right now. The general mob filters (passive/neutral/hostile/etc.) do apply to modded mobs too, but we don't have a setting where you can select a list of specific mob types in the same way as the block types in X-Ray.
That would definitely be a useful feature to have though! If you or anyone else wants to implement this through a pull request on GitHub, I'd be happy to review it and merge it into Wurst.
