Interestingly, I disagree, and I would love to hear your thoughts on why. I will say that I rarely see anyone who proposes that God created the universe go into detail about the mechanisms of how this was done, but that doesn't mean that no such mechanisms have ever been supposed.
However, in order to go into detail about the mechanisms through which God created the universe, we first have to reject naturalism in favor of either metaphysical idealism or mitigated dualism. While this is a stretch for the scientifically minded and the skeptical critical thinker, this is also the territory that the concept of God resides in the vast majority of the time. It is only once we settle on one of these metaphysical concepts that we can begin proposing a mechanism for how God could give rise to the physical universe.
If you think about it for a second, this is sort of inevitable. The question of what physics is and how it got here is not a question within the physical sciences themselves but about physics, thus meta-physics. So any potential answer we can give, whether it's from naturalism, idealism, or dualism, it will be within the domain of metaphysics. Now, you can attack the methods of metaphysics as well as how justified its conclusions are, but once we start asking metaphysical questions it becomes a conversation about metaphysics.
Simply arriving at idealism or dualism is not enough, of course. We would have to go a step further and propose specific mechanisms for which the ideal can interact with or induce changes in the apparently material. We also have that! It's called manifestation.
Think about it this way: have you ever daydreamed or had a lucid dream where you could add and subtract objects to your mental image? By visualizing something, it gains form within the mind. Idealists posit that our entire universe is in the mind of God, and so God did the same thing when they created the universe; they visualized it and it manifested.
Theologians like George Berkeley call this "immaterialism." If it weren't for God continuing to dream up what we perceive as a material universe, we would stop existing within their mind and thus stop existing entirely. In this way, God not only created the universe, but continues to sustain it by holding on to the mental images of everything within it. This also explains how God is both omniscient and omnipotent: they know everything because everything is contained within their mind and they're omnipotent because they're essentially lucid dreaming on a cosmic scale.
Immaterialism is one example of how idealism solves this problem of a mechanism. Mitigated dualism tends to apply the same general principle, just with added steps that only really make sense after doing some fairly specific visualization exercises.
I was going to get into how this provides philosophical justification for occult and New Age concepts of magic, which use additional mechanisms that rely on this core idea, and how they're linked to the general concept of receiving synchronous "signs from God," but my post is already getting too long. We can discuss immaterialism more and how it provides a mechanism for creation if you want.
Of course, immaterialism is unfalsifiable, but our current understanding of the world makes it highly likely to be false since we know that matter generates mind, not the other way around. However, it does provide philosophical coherency to the metaphysics of theology, which is pretty much exactly what you're asking about here.
