Subscription objects have a schedule property that will have a schedule's ID if it is being managed by a schedule https://stripe.com/docs/api/subscriptions/object#subscription_object-schedule

will I not be able to set the trial on a subscription directly if it has subscription_schedule property?

I think you still can but that will basically update the subscription's first phase

And sometimes that change happens in ways that don't make sense for your integration

So I'd say try this out in test mode to see how it affects your trial and schedule
