Is it possible to render framebuffer from another entity's camera without displaying it on screen?

I'm trying to make a camera peripheral block for computercraft (1.18.2 forge), but stuck at the start now

I want it to create a virtual camera entity, then return what it sees as imageBuffer so that it can be displayed by monitor from Tom's peripheral mod.

So first I tried using a specific entity as the carrier of camera.

I tried save the original mainRenderTarget, then create a new RenderTarget(or framebuffer) when RenderHandEvent fired, then use setCameraEntity to move the camera to that specific entity, render what it sees and write it into the new RenderTarget.

I did get the view from that entity as bufferedImage, then save it as a png file. 

But in game, both entity's camera view and player's camera view were displayed. Is it possible to render a entity's camera view without displaying it on screen?

      Minecraft server Bewitchment Mod error Could not execute entrypoint stage 'main' due to errors, provided by 'bewitchment'! Cause

      By WorstLuck · Posted

      I know this is a forge only place, but just to be clear, my error is in Fabric I was actually super frustrated while trying to fix this, like this mod does work when I play it by launching it in minecraft, but when I was trying to install it onto the server it just kept crashing so I decided to delete every mod I've got but kept the bewitchment mod and the necessary mod it needs to function and I tried to run the server... But it somehow still crashed, and the thing is that I really do want the bewitchment mod to be in the SMP so it'll be SUPER helpful if anyone can figure out on how to fix this: It didn't give me any "crash-reports" so I'll be sending the logs and what the console said: Console: [18:51:46] [main/INFO]: SpongePowered MIXIN Subsystem Version=0.8.5 Source=file:/home/container/libraries/net/fabricmc/sponge-mixin/0.13.3+mixin.0.8.5/sponge-mixin-0.13.3+mixin.0.8.5.jar Service=Knot/Fabric Env=SERVER [18:51:46] [main/WARN]: Error loading class: io/github/apace100/origins/power/PreventItemUsePower (java.lang.ClassNotFoundException: io/github/apace100/origins/power/PreventItemUsePower) [18:51:46] [main/WARN]: @Mixin target io.github.apace100.origins.power.PreventItemUsePower was not found bewitchment.mixins.json:integration.origins.PreventItemUsePowerMixin from mod bewitchment [18:51:47] [main/INFO]: Initializing MixinExtras via com.llamalad7.mixinextras.service.MixinExtrasServiceImpl(version=0.3.5).
