How do I rollback the nether with coreprotect?

I have a server where I want to be able to rollback a 750block radius around 0, 0 in the nether. This way, I can "reset" the nether so that ancient debris never run out. Does anyone know how I can do this with CoreProtect? If there's a command for it, what command would I use? And would I have to be in the nether whilst using the command?

(For those who might say: But why don't you just make the world border infinite instead of resetting nether? I want my server to have a set world border, and I want to be able to reset just the nether).

Just type this command: "/co rollback #global t:<time>h"

(<time> must be a value).

Won't that rollback everything tho? Like it'll rollback the overworld, end, and nether, instead of just the nether?

I tried the command and for some reason #global only rolled back a radius of 10... I'm confused to what happened, do you know what went wrong by any chance?

A radius of 10 isn't enough though. It needs to be like 100 or 200 +, but it can cause lags.

Yes, ik a radius of 10 isn't enough, I copied your command and for some reason, it onnly rolled back a radius of 10, even though the command says it to roll back #global. For some reason, #global didn't rollback @global, instead it only did radius of 10 even though I didn't type radius of 10. I will try just doing radius of 100 or 200 since @global didn' work for some reasoon
