I’m not willing to say that anything signifies dyslexia in a 23-month-old. That’s kind of like saying a 16-year-old who forgets her lunch money has pre-Alzheimer’s. I think your son is just struggling with producing the words he hears and gets a little mixed up.
It may just be the examples you gave, but there is a pattern to his mispronunciations. “P” and “B” are made in the same way by the lips, but the “P” uses only breath and the “B” adds voice. They are called “breathed” and “voiced” consonants. Make those two sounds yourself and you’ll see what I mean. Now do that with “K” and “G.” Exactly the same thing. Mouth movements required to make both sounds are the same, but one uses only the breath and the other adds sound from the throat.
“G” and “K” are a little harder in general, as we can’t see how they are made the way we can with “P” and “B.” These are hard distinctions for little children to make, and your verbal son may just be struggling with them. Be patient with him now. And I wouldn’t correct him if he says, “gip.” Find an excuse to say it correctly rather slowly and distinctly, and in time he will probably correct it on his own. The important thing is that he is talking and using sentences longer than could be expected on the basis of his age.
