Is the package manager for php Composer decentralized like Maven for example?

Question

Composer

The question is, is it possible to create a package repository, for example, on a local network or on some resource on the Internet and "pull" dependencies for your application from this repository? As far as I know, the Maven architecture allows you to do this and it is used, for example, in banks, since for them it is a critical part of the reliability of systems.
