reset s7-1500 not working

And I tried with an empty project, downloading an empty code but it doesn't change anything. I have the impression that this is a configuration due to the code with which the system came, however how can I modify this so as not to have any active outputs when I do not have them activated.

Here you will find the procedure to follow: Resetting the CPU to factory settings

If so, you cannot remove those or disable those at the module level. You would need to manually disable very digital channel one by one. What is wrong with the DigIn/Out LEDs accurately reporting whether they are current on or off?
