Looking for VPN FREE PLUGIN

hi, who is capable would be so kind to compile a working and self-starting Zerotier plugin (.ipk) for Zgemma with OpenATV 7.5 (armV7). I tried, but I failed. It seems strange to me that no one who has the skills to do so has ever created a plugin that allows you to intervene on a decoder remotely with for example WinSCP using Zerotier or Tailscale to be able to modify files. I think it would be very useful. I thank anyone in advance who wants to help in this direction.
