无法删除根 url 路径的 index.php

Question

我都用

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [QSA,L]

或最近：

FallbackResource /index.php

拥有 Web 应用程序的单一入口点 (/index.php)。

但是我无法删除应用程序根 url 路径的 url 中的“index.php”：

https://www.test.com/contacts    works (as for all other endpoints below the root)
https://www.test.com             rewritten as https://www.test.com/index.php
https://www.test.com/            rewritten as https://www.test.com/index.php

https://www.test.com/index.php   if possible should be rewritten as https://www.test.com

有没有办法保持 url 根路径“干净”？
