No way to disable deprecation message logged to file
Any call to GeneralUtility::deprecationLog creates one line:
20-03-2019 05:26: GeneralUtility::deprecationLog() will be removed in TYPO3 v10.0, use "trigger_error("Given reason", E_USER_DEPRECATED);" to log deprecations.
This line is written even when following option is set:
$GLOBALS['TYPO3_CONF_VARS']['LOG']['TYPO3']['CMS']['deprecations']['writerConfiguration'][\TYPO3\CMS\Core\Log\LogLevel::NOTICE] = ;
Usually some plugin like news, vhs, etc call GeneralUtility::deprecationLog()

@ Katharina Strasser About deprecations in 10. I am not aware of a problem there currently. The functions that were used to write in var/log/deprecation_<hash>.log have been removed in 10.
Deprecation logging via the logging framework can be disabled (and should not be logged in the production context because they are level NOTICE), see https://docs.typo3.org/m/typo3/reference-coreapi/master/en-us/ApiOverview/Deprecation/Index.html#disabling-deprecation-errors
