Disable lag when using caps lock key to toggle input language

I have my caps lock key set to toggle input language between English and Russian. There's a slight 'lag' — I have to hold it down for slightly longer than a "normal key". If I press it quickly, as I do when press the keys when typing this message for example, it doesn't toggle the input. This is annoying because I need to constant switch between input methods, and I want it to be instant. I would be happy to disable the traditional function of the caps lock key if it means I can achieve this. I'm using a MacBook Pro 14,1 on Monterrey.
