Is there a way to block commits?

I notice that PhpStorm would notice TODO: marks and warn you before commiting. Is there an equivelent "@nocmmit" tag I can use to outright stop a commit from happening on a file? Often, I want to go ahead and commit TODOs, so I would often ignore the TODO and Warning messages. However, in instances I specifically do _not_ want to commit a file, I want to block myself from accidentally committing it.

I found a thread talking about using the syntax highlights to call-out @nocommit blocks. However, I'm not finding an option that would outright block a commit. Is there such an option?
