Is there any Hook for button?

Hi,

I've made a custom SVG icon library, with CPT. I'm able to call my SVG icon using PHP into function.php (only: I can't add php directly into wordpress editor).

I would like to know if there any way to Hook all <button> </button>. My plan is to add SVG icons into the tag <button> </button>.

I could use shortcode... but I tend to avoid it since I discover it descrease speed load.

thanks
