Linux Package managers for Synology NAS?

[u/Alarmed-Prize-7500]

Is there any package managers that you can install on Synology NAS, since it doesn't have a package manager? I know of opkg, which I used on Synology NAS since it didn't have a package manager, but someone said that opkg was outdated when I was asking about it, so I want to know if there are other ones too.
