Morality and nothing else

To the Rabbi Shalom
After hearing the distinction the rabbi makes between moral values ​​and religious values, both of which can be independent and at the same time come from God's will, the following idea (very difficult for me as a religious person) occurred to me:
If we believe in God, it is indeed logical to say that He wants us to be moral, since He has clearly imposed moral values ​​on us. It is even logical to say that He also expects those who do not believe in Him to be moral, since He created them with the knowledge of moral values.
But why should we believe that he expects us to practice any religion?
After all, he did not impose religious values ​​on us, and we are forced to rely on testimonies from hundreds or thousands of years ago and/or on various signs, which, even if these are serious testimonies and signs, are not at all difficult to find a refutation of.
It is actually logical to say that God is not interested in any worship, religion, prayer, or law. "Who told you to do this?" He could ask. And this, again, is contrary to the moral values ​​that He did reveal to us.
In other words, if God wanted us to uphold other values ​​besides moral values, why wouldn't He reveal them to us as clearly and directly as He revealed moral values ​​to us?
