I understand that i can load it along side it. But it would be nice to have inside of steamos and just click on it from the library. It seems that RetroArch is jumping on it. That's why I asked, but they seem to be doing it from the windows point of view. like i said it would be nice to have it support in steam not a side load. that's all.

So I am going to say installing the SteamOS driver is probably a bad idea seems to have broken standard functionality. Specifically after disabling and removing the driver.
Having to rekick now to get it back to normal.

When attempting to launch lr-picodrive from inside emulation station that is launched from SteamOS.

SteamOS is just Ubuntu so the existing instructions should work:
