Resolved How do I change my HDRP Defaults Settings Profile?

yay HDRP. Manual says just add post processing to volume, like any other volume component. WRONG.
There is this little bugger called HDRPDefaultSettingsProfile that already has some goodies in it. So when a manual trusting user turns on post processing, even without checking any other boxes in HDRP default settings, all these extra post processing effects show up out of nowhere, I got bloom, motion blur, vignette, and a couple others. Took me at least a good hour to figure out what was going on.

So I finally figure out that it is HDRPDefaultSettingsProfile diddling my postprocessing stack, and I get all mad, and go to change my HDRPDefaultSettingsProfile to nuke all that unwanted garbage... ...and it is grayed out. Not gonna let me touch it.

FINE, I'll just CTRL+D to duplicate, make my own. NOPE, wont duplicate.

So How do I change my HDRP Defaults Settings Profile?

However, mien is all grayed out, but I am seeing that it can take any volume asset, so I guess I'll just make my own default volume asset, and swap. I dont know why (or technically how) the default is not editable or copyable.
