How to set the composer version

[KptMonkey]

Hi,

I am curious about how to set the composer version since my application requires v1.x. I added the line set('composer_version', '1.10.17'); to the deploy.php file but during the process, it still curls the current version (2.0.7).
It looks like that it gets overwritten in vendor.php. Since it's not a bug ticket, maybe there is another solution that will do the trick. I am not the only who has this problem https://stackoverflow.com/questions/64767217/php-deployer-change-composer-version (I added one comment to this thread)
I tried it with the deployer version 6.8 and the current beta

Just install the correct Composer version of the host and Deployer will use it.
In Deployer v7 it's possible to specify composer_version config and Deployer will download it and place under .dep/composer.phar.
