How can I make violation os [StringFormatMethod] warnings show up as errors instead?

I've recently discovered [StringFormatMethod] and I love that Rider helps underlining them and show up as a warning, but I'd much prefer them being red underlining as errors and in the Problems window also showing up as a serious problem that needs to be fixed. 

I feel like this is a setting I've seen somewhere, but can't seem to find. Would be even more helpful.
