Per my test, setting validation on start time and end time dropdown fields by using Power Apps is not available.

As a workaround, you could use list validation in the list settings.

List validation: =IF([start time]<[end time],TRUE,FALSE)

Result:

---

Update:

1. Create start time and end time dropdown fields in the list.
   
   
2. Go to List settings -> Validation settings -> List validation: =IF([start time]<[end time],TRUE,FALSE)
   
3. If the start time is greater than the end time, error message will show in the form and you cannot submit the form.
