I am going to answer the question in your title because I am unsure what you are asking in the post.
The website Eka’s Portal has a handful of mods posted. A list of all publicly available mods to my knowledge and where they can be found:
Aon - Included along with VT+
Adder - Included along with VT+
Netcaster - Included along with VT+
ARK - Included along with VT+
Yoimiya - Link can be found on Eka’s.
Holstein - Dedicated post created by Crimson on the game’s community page.
Chimera - Included with base game v0.12+ (Patreon Only)
To my knowledge most mods are shared in the game’s Patron-only Discord server.
