Remove Paper's Built-In Anti-Cheat ($$$)

[Cranked]

I own an upcoming factions server. There is a mod called schematica, if you don't know what it is a client-side mod that allows you to save schematics and create blueprints in the server. It also has a "printer" feature, in which it will automatically build the schematic for you. Some faction servers allow it and others don't, mine obviously will. The lower/slower settings of schematica work on my server, but I want to it work flawlessly, as you can see here:

However, when I test it on my server, it glitches/lags back and prevents it from working. I know for sure no plugin/anti-cheat plugin is causing the issue as I tried with no plugins installed and it still doesn't work. I have also tested it on a vanilla minecraft server, and it works perfectly there. So, I have reason to believe that something inside of paper spigot is causing the issue, maybe like a mini-anti-cheat?

This is a thread on spigotmc.org which talks about how to remove it: https://www.spigotmc.org/threads/disable-built-in-anticheat.213313/
"The default spigot anticheat can be found in PlayerConnection.java You can edit and recompile the server (or use instrumentation) to remove/edit this."

Paper Spigot, obviously, is a fork of Spigot and may be slightly different, but I basically need you to remove this "built-in anti-cheat".

Technically, I am paying for schematica to be fully fixed, with the following schematica settings to work: delay=0, range=5, and adjacent block placing only set to false.
