Can't update Node.JS version on Gamelift fleets,manual update overrides with the almost deprecated version (Node v10)

Is there a way to update Node.JS version to 14 or 16 on AWS Gamelift ?Our fleet runs on Amazon Linux 2 OS . Tried to do it manually on the existing fleet, but it is not compatible with auto generated GameScaleLightweight NodeJS server, so it won't activate the fleet. Tried to create new fleet with new Gamelift build, included node install in the install.sh script, but it didn't install at the specified directory( which was /local/NodeJS ), but a level lower (and i didn't messed up the path). Instead, on specified directory, there was NodeJS version 10 (which was clearly created by Gamelift) Tried to create new fleet with new Gamelift script, that didn't work either. Every time the result is the same, Node.JS version is still 10. Right now, the only thing that works is, revert to AWS SDK v2 , which supports Node.js version 10...
