God ki is one of those things that has never been fully explained in detail and seems to lack consistency in the way it's presented, so we can't really say anything conclusive about it other than it can't be sensed by normal people
This is halfway true. While it should not be sensed by mortal beings, some of them were able to, like Vegeta, Freeza, Hit and Jiren in the anime, for unknown reasons. We don’t know if they say this because they can really sense it or if they are guessing based on the pressure they are feeling. But you are right that consistency is lacking.
In the anime, Whis explains they need to raise their ki as much as they can without letting it leak out from their bodies, but this doesn’t explain how they start emitting another type of ki. They only naturally realize SSB’s power is there by doing so. Also, in the special dimension within Whis’ staff they can only move around if they manipulate their ki like that, because of the immense pressure of the god ki that is there. This only reinforces the idea that mastery of ki manipulation is required to enter that realm, but the more technical aspect of how their ki become more pure or how they emit a super heavy aura is conveniently left unexplained.
In the manga, it doesn’t seem like they went this route, at least not initially. This tweak only became a key attribute to complete SSB, not access it. Later Vegeta pretty much abandons this concept when he unlocked SSBE. Besides, it seems that deities have to undergo some specific training to attain god ki, like Hakaishin and Kaioshin’s candidates and Dende. Oob is also an unique case, as he inherited god ki from Pure Boo, who stole it from Grand Kaioshin after the split.
Considering all this, honestly I think it’s not impossible for Goku and Vegeta to start using god ki in their regular forms, but, at least until now, it seems to be exclusive to transformations.
