I updated my shroud on my hot end which pushed my BLTouch farther to the left of the nozzle. It seems currently i cant set my ABL offset beyond -50x which has my BLTouch reading the far front left side of my board which is making it difficult to level the left portion of my board. What can i do here to alter this? Looking at the shroud setup documentation i need to use something around -63x, but it seems to only use -50x even when I use a g851 command to set it.

I can’t seem to find anything in the Marlin source that would limit the X offset (which gets stored in `probe.offset_xy.x`) to any specific value.
If you run M851 (Note: Not _G_851) via a USB port, does it show the correct value?
Keep in mind, on the Ender 3 V2, the build area is slightly offset due to physical movement limitation - so it won’t always be exactly the in the centre of the bed.
If you manually move the nozzle to the centre coordinates of the bed, does that appear to go to the same place as the probe does?
