The commandment of faith in God

But this is a very logical thing to say, so how is it possible that none of the commentators paid attention to this question, (and in general no one in the general religious community paid attention to this question) Maybe it's because they were afraid that this question would arouse heresy because it follows that it is possible to keep the Torah and commandments even if you don't believe in God. Does this sound reasonable to you or is this a baseless argument?
(Although this is more of an explanation for why no one asked this question than why belief is a commandment)

You're taking me into the realms of psychology. I have no interest or skill in that field.

The Book of Mitzvot was originally written in Arabic, and in the Hebrew translation of the first mitzvah, the word ‘faith’ is a bit confusing because in its original Arabic translation it is ‘to be convinced’, and not necessarily to believe in the religious sense.
It is certainly possible that this is what Maimonides meant. You cannot command someone to believe in facts, but you can certainly command them to investigate those beliefs in order to reach conviction.
What Maimonides would say about someone who investigated and was not convinced is another discussion.

I think belief is a choice. Usually unconscious, but it is still a choice. Those who understand NLP and know how to control the subconscious through various actions can perhaps understand better. For example, why I say that belief is a choice: When I meet someone on the street and ask their name and they answer me Yossi, then when I say to myself, oh, that's not Yossi, he's lying, I chose not to believe, and vice versa, and that is also essentially faith, this choice to be convinced that it is true.
