Which Minecraft shader does LarsLp use?

Hi! Do you know what kind of Minecraft shader LalsLp uses (Bedrock version)?

There are no shader packages on the Bedrock version, only RTX. This is a feature that can be easily activated, but you need an RTX graphics card for it.

Here is the FAQ on the Minecraft homepage: https://help.minecraft.net/hc/en-us/articles/360053235571-Minecraft-with-Ray-Tracing-FAQ

You can only use Schader (as resources) (without graphics card) Here is a download:

I think that LarsLP uses the already mentioned RTX. He's got a couple of videos about it on his channel and I think he mentioned that every now and then
