How do I invoke the import in an updb hook?

I want to invoke the import in an update hook. ideally , I want to store the generated taxonomy in a file and in my hook update pass the content to structure sync import function. Something like this:

function my_module_update() {
  $tax_list = get_the_list("path/to/my/file.yml");
  TaxonomiesController::importTaxonomies($tax_list, "full");
}
