Hello. I tried to find out myself, but forgive me for my stupidity, pages like this
https://docs.backdropcms.org/api/backdrop/core%21includes%21common.inc/function/backdrop_get_html_head/1
tell me absolutely nothing (why is documentation always so inhumane?).
In short, all I need is to add the phrase “user-scalable=no” to the “viewport”, otherwise my theme does not behave correctly on mobile devices. Please, tell me the right way to do this (if possible with detailed comments, I hope this will be useful to many).

I think the function you actually want is hook_html_head_alter
Something like:
function theme_name_html_head_alter(&$head_elements){
$head_elements['viewport']['#attributes']['content'] .= ', user-scalable=no';
}This adds it to the existing content of the viewport meta tag.
