The use of modular routers in claimed chunks does not work, ftb chunks has a feature to give the modular routers chunk perms, i didnt know if the same thing was possible here.

Haven't used it but at first glance seems like a case of "static" fake players, which you can configure in the main config file.
Please read through the comment above that option.

The fake player name seems to be "[Modular Routers]".

okay thank you, ive looked further into modular routers as well, and i found a security upgrade that makes the router act as the player

I see, yeah I saw that in their code too. Wasn't sure how accessible that was.
