PHP-FPM Disable some PHP extension

Having this on config:

Code:

PHPDEBUGMODE=n               # --enable-debug PHP compile flag
PHPFINFO=n                   # Disable or Enable PHP File Info extension
PHPPCNTL=n                   # Disable or Enable PHP Process Control extension
PHPINTL=n                    # Disable or Enable PHP intl extension
PHPRECODE=n                   # Disable or Enable PHP Recode extension
PHPSNMP=n    

Will not install all this extension right?
