The answer is to understand the Drupal templating system. Any Twig template on Drupal can be overridden with the current theme by copying the Twig-template into your theme and overriding the template content. You can also use theme_hooks with modules to override templates in modules instead of themes.
Take a look at the documentation: https://www.drupal.org/docs/theming-drupal/twig-in-drupal/working-with-twig-templates
For your specific link-Template you can use:
- core/modules/system/templates/links.html.twig
or depending on your base theme:
- web/core/themes/classy/templates/navigation/links.html.twig
- web/core/themes/olivero/templates/navigation/links.html.twig
- web/core/themes/stable/templates/navigation/links.html.twig
- web/core/themes/stable9/templates/navigation/links.html.twig
- web/core/themes/starterkit_theme/templates/navigation/links.html.twig
