@Sharlan0i don't recommend Smart Pricing for anyone. But with it off, you're free to manually enter any price for any date that you please, or to use a range of pricing tools that activate your preferences throughout the open calendar dates.
I suggest taking some time to familiarize yourself with all the variables in the calendar settings, and looking at how the the results play out in the calendar. If anything looks off to you, you can always manually adjust it. Also, if for some strange reason you feel attached to "smart" pricing, you can apply it to some dates but deactivate it for others.
The point is, you are in full control of how your listing is priced.
