HDRI Map rotation in Blender could be easier, much easier done. I like how it works in Marmoset Toolbag or inside Substance Painter, where I just click shift and drag and it spins around my 3D scene. With free Rotate an HDRi plugin created by Alexander Belyakov, you don't have to set it up on your own. You can download an addon for free from Gumroad
Add some hdri to the World Output, and install, enable the plugin. Now just click CTRL + ALT and drag the mouse to rotate HDRI Map. It works in Eevee and in Cycles, in Material Preview mode and in Render Preview mode. You can customize default hotkey in addon's settings.
