Foods forbidden to Gentiles

Hello Rabbi,
 
Recently, awareness has been raised (and it’s a good thing) that some people in China practice eating animals while they’re still alive. And of course, there’s the whole idea that this might be why there’s coronavirus, etc. Of course, as someone who advocates for divine intervention in the world, I personally have no ability to conclude whether this is true or not, and so I’m less concerned with it.
My question is about eating dead animals. I hear a lot of religious people saying very critically, ” These Chinese eat snakes, cats, bats, and dogs.”
Eating bat meat does sound like an extremely disgusting thing, and eating dog meat sounds like a morally shocking thing.
But can we conclude that there is some prohibition (and even an indirect prohibition) for Gentiles, from the Torah of Israel , to eat the meat of bats or dogs when they die?
If there is no possibility of deducing such a Torah prohibition, and assuming that there is no prior scientific knowledge that bat meat is more dangerous than cow meat, for example, do we as the spreaders of the gospel of God in the world (with Segula) have the mandate to oppose the phenomenon of eating bat meat (for example)?
Best regards, Ehud
