Unity provides two prebuilt render pipelines based on the Scriptable Render PipelineA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info
See in Glossary (SRP): the High Definition Render Pipeline (HDRP), and the Universal Render Pipeline (URP). HDRP and URP offer extensive customization options; however, if you want even more control over your rendering pipeline, you can create your own custom render pipeline based on SRP.
Read this documentation if you want to create your own custom SRP, if you want to create a custom version of URP or HDRP, or if you want to understand how SRP works on a fundamental level.
