Shaders are a feature of the popular visual mod called Optifine. However, since Minecraft 1.20.5 is still fairly new, the development of Optifine for it is yet to be completed.

For Iris Shaders (for modern visuals and fabric users), go to the Iris Shaders page— https://irisshaders.net, download the Fabric version for 1.21.5, and then install it using the Fabric mod loader.
