Unity provides two prebuilt render pipelines based on the Scriptable Render Pipeline (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.
