Installing HDRP when I started w/ URP

[vague hemlock]

I'm not too far along, just a custom player controller and state management system. Nothing graphics, level or lighting wise.
I want to mess with shaders, and I realized I should've started with HDRP.
Is it safe at this stage in the project to install the package? Will it automatically... do what it needs to do? haha Thanks for the help.

Not everything, you'd also need to specify it as active and run the render pipeline converter (which iirc is the "HDRP wizard" in HDRP context) to convert the graphical assets to correct render pipeline
Which is an irreversible process so do a backup
It might also not include everything, like some default HDRP assets, though not too sure of that
I'd prefer to make a new project in HDRP, and just move your assets as an .unitypackage into the new project to skip the hassle

You'll still likely need to run the automatic converter but only to update any placeholder assets you might have, but it's much simpler than installing HDRP in my opinion
