Is there a way to remove the option to put time estimation on stories? (put the time estimation only on the sub-tasks of the story)

Hi @Eleanor and welcome to the community!

Yes - This can be done by updating the respective screens.  On the Story screen, you would remove the time field(s) in question (Time Tracking, Original Estimate, etc.) and on the Sub-Task screen you would add the field(s).
