Unlink steam and keep my EA

Hey, I want to buy my Poe 2 EA supporter pack via steam, and then link my steam account to a path of exile account (like this one). Will the EA be asociated to the new linked Poe account or will be linked to my steam? Meaning if I unlink my steam I barely use and want to use the standalone client the EA purchase will keep available on my poe account?

Thanks you.
