GNSS dealing with GPS cold start

[nintyninebottlesx]

I am using gnss generic driver and it works great.
However the GPS module itself takes about 26 seconds to get a lock on a cold startup.

So when I boot up my device sometimes it gets a lock sometimes not . Sometimes eventually it might callback in the future sometimes not What's the best way I can deal with this? Should I try using SYS_INIT() with a delay . Or can I delay the GNSS callback?
Thanks much for any insights.
