Hide or remove links in Get New Psw Page

You should be able to find the container (div most likely) these links are in and set it to ‘display: none’. If they aren’t in the same container, you can just set each link to ‘display: none’. For the container method:
div.class a {
display: none;
}

There is an article about this here: https://codex.wordpress.org/Customizing_the_Login_Form

Alternatively, you can also try using plugins that can change this page. Example: https://wordpress.org/plugins/login-customizer/
