I have a RS Blazer ‘19 and I needs some suggestions of how to protect my capless gas tank from tampering. Any suggestions?

I know the Chevy Silverado has a Security Cap, what’s GM going to do for other models?

I haven't tried, but I'm pretty sure they are anti-siphon fill necks. Or at least I hope they do.
