That should be it, delay is already 15 seconds by default although you could try with steam_api64.dll instead of the overlay .dll file as a more direct well I don't know what to call it but that particular file is specific to every game on Steam and part of the game folder whereas the overlay is set for the steam client itself.
I'm not sure it would make a major difference though it is possible that steam_api64.dll is loaded earlier into the entire process than the overlay .dll is (Or say the steamclient64.dll) thus this is registered earlier and Afterburner / Rivatuner triggers it's delay action.
Aside from the Steam API or rather Steam overlay problem (On Valve's end as I've understood it.) the default profile already has a workaround for certain Nvidia effects causing problems with the OSD functionality, I'd assume TXAA specifically but it's possible other Gameworks functionality could also be needing this compatibility feature.
EDIT: As to why the Steam overlay is being problematic I'm not too sure on the specifics on that and why Valve hasn't been particularly bothered to fix it on their end instead, far as the Steam API goes that's probably pretty complex with a variety of different versions going from older games with less functionality to the newest games making use of e.g Steam VR and it's gamepad along with expanded support for Vulkan and D3D12 to name some things but I'd assume that if this overlay issue required some more extensive work on the Steam API to solve well Valve can't force developers to patch their games to implement newer builds of this so that would be my guess but it could just as easily be that the overlay functionality could be separated without too much effort on their end and they're just not seeing it as a high priority ensuring compatibility even with more popular third party software.
Valve does a bit of whatever they want lately or so it would appear at least although it can come back and bite them in the ass too such as a recent ruling in Australia ending with a fine against them being about 10 times higher than what Valve had initially suggested to settle for though I doubt it'll change anything.
