It's due to the default revalidate frequency set for 180 seconds

PHP: OPcache - Manual

PHP: Runtime Configuration - Manual

opcache.validate_timestamps boolean

If enabled, OPcache will check for updated scripts every opcache.revalidate_freq seconds. When this directive is disabled, you must reset OPcache manually via opcache_reset(), opcache_invalidate() or by restarting the Web server for changes to the filesystem to take effect.

opcache.revalidate_freq integer
How often to check script timestamps for updates, in seconds. 0 will result in OPcache checking for updates on every request.

This configuration directive is ignored if opcache.validate_timestamps is disabled.

You can exclude a file or path from Zend Opcache caching completely via blacklist option too

opcache.blacklist_filename string

The location of the OPcache blacklist file. A blacklist file is a text file containing the names of files that should not be accelerated, one per line. Wildcards are allowed, and prefixes can also be provided. Lines starting with a semi-colon are ignored as comments.

A simple blacklist file might look as follows:

; Matches a specific file.
/var/www/broken.php
; A prefix that matches all files starting with x.
/var/www/x
; A wildcard match.
/var/www/*-broken.php

To customise Zend Opcache settings see the instructions to create your own .ini settings file to retain the changes at https://centminmod.com/phpfpm.html#customphpini

Example order of php .ini files applied via php --ini command
Code (Text):
php --ini
Configuration File (php.ini) Path: /usr/local/lib
Loaded Configuration File:         /usr/local/lib/php.ini
Scan for additional .ini files in: /etc/centminmod/php.d
Additional .ini files parsed:      /etc/centminmod/php.d/a_customphp.ini,
/etc/centminmod/php.d/curlcainfo.ini,
/etc/centminmod/php.d/geoip.ini,
/etc/centminmod/php.d/igbinary.ini,
/etc/centminmod/php.d/imagick.ini,
/etc/centminmod/php.d/mailparse.ini,
/etc/centminmod/php.d/memcache.ini,
/etc/centminmod/php.d/memcached.ini,
/etc/centminmod/php.d/redis.ini,
/etc/centminmod/php.d/zendopcache.ini
If i want to override opcache.revalidate_freq 180 seconds default, I'd create a .ini file after /etc/centminmod/php.d/zendopcache.ini alphabetically i.e. /etc/centminmod/php.d/zzendopcache.ini

So ordered after zendopcache.ini
Code (Text):
php --ini
Configuration File (php.ini) Path: /usr/local/lib
Loaded Configuration File:         /usr/local/lib/php.ini
Scan for additional .ini files in: /etc/centminmod/php.d
Additional .ini files parsed:      /etc/centminmod/php.d/a_customphp.ini,
/etc/centminmod/php.d/curlcainfo.ini,
/etc/centminmod/php.d/geoip.ini,
/etc/centminmod/php.d/igbinary.ini,
/etc/centminmod/php.d/imagick.ini,
/etc/centminmod/php.d/mailparse.ini,
/etc/centminmod/php.d/memcache.ini,
/etc/centminmod/php.d/memcached.ini,
/etc/centminmod/php.d/redis.ini,
/etc/centminmod/php.d/zendopcache.ini,
/etc/centminmod/php.d/zzendopcache.ini
In /etc/centminmod/php.d/zzendopcache.ini add value say 10 seconds
Code (Text):
opcache.revalidate_freq = 10
Note though reducing revalidation frequency lowers performance of caching all the time 24/7. Best way is just to restart php-fpm and nginx after file updates which are done manually via command shortcut
Code (Text):
nprestart
After restart recheck value is now at 10 seconds
Code (Text):
php --ri 'Zend OPcache'
