Custom header content in customizr

I have custom header content that I generated for favicons and bookmarks across different platforms. I want to add it to the the head element, but I’d rather not put a custom class-header-header_main.php file in my child theme since that content has already changed once since I’ve been using Customizr, and I’d rather not have to keep watching for those changes.

So, is there any way to add elements to the HEAD element without customizing that file? Below is the content that I’m trying to add.
