So I learned that if a MicroSD card gets snapped in half, its unrecoverable.
Okay, so suppose you were in war, and enemy soldiers were about to raid you. You just snap the cards in half and the data is un-recoverable, right?

Your best bet would be to shred the data multiple times (for example with the shred command) and then break the card physically. But shredding takes time so I guess that’s not very applicable to your case.
If you have a lighter, you also can try to melt the SD card’s insides. That should be impossible to recover.
In any case, you should keep it encrypted all the time and only decrypt it on the fly. For example with LUKS2.
I was going to say burn it too.
And if you really want to burn it good look into getting/making thermite.
