About php : Changing-php-fpm-values-in-the-local-php-userini

In my /etc/php-fpm.d/www.someweb.com.conf, I have the following configuration:

php_admin_value[upload_tmp_dir] = /home/www.someweb.com/tmp

Is there a way to change these value in my local .user.ini?

Kind of:

upload_tmp_dir = "/home/www.someweb.com/tmp"

No, you can not change values which are not changeable, e.g Named: PHP_INI_SYSTEM. – See official documentation: https://www.php.net/manual/en/ini.list.php
