Try full path to composer

whereis composer

Once you know path

php -d memory_limit=4G /opt/cpanel/composer/bin/composer update -vvv


You can try below command

COMPOSER_MEMORY_LIMIT=-1 composer update

Hope this will help you!!

This is the way you can write composer command and it will resolve the issue.
